In , Karl Ferdinand Braun introduced the cathode ray tube as part of an oscilloscope , a crucial enabling technology for electronic television. Two years later, Robert von Lieben and Lee De Forest independently developed the amplifier tube, called the triode. In , Albert Hull developed the magnetron which would eventually lead to the development of the microwave oven in by Percy Spencer. In , Konrad Zuse presented the Z3 , the world's first fully functional and programmable computer using electromechanical parts. In , Tommy Flowers designed and built the Colossus , the world's first fully functional, electronic, digital and programmable computer.
The arithmetic performance of these machines allowed engineers to develop completely new technologies and achieve new objectives, including the Apollo program which culminated in landing astronauts on the Moon. The invention of the transistor in late by William Shockley , John Bardeen , and Walter Brattain of the Bell Telephone Laboratories opened the door for more compact devices and led to the development of the integrated circuit in by Jack Kilby and independently in by Robert Noyce.
The microprocessor was introduced with the Intel Electrical engineering has many subdisciplines, the most common of which are listed below. Although there are electrical engineers who focus exclusively on one of these subdisciplines, many deal with a combination of them.
Sometimes certain fields, such as electronic engineering and computer engineering , are considered separate disciplines in their own right. Power engineering deals with the generation , transmission , and distribution of electricity as well as the design of a range of related devices. In many regions of the world, governments maintain an electrical network called a power grid that connects a variety of generators together with users of their energy. Users purchase electrical energy from the grid, avoiding the costly exercise of having to generate their own.
Power engineers may work on the design and maintenance of the power grid as well as the power systems that connect to it.
Power engineers may also work on systems that do not connect to the grid, called off-grid power systems, which in some cases are preferable to on-grid systems. The future includes Satellite controlled power systems, with feedback in real time to prevent power surges and prevent blackouts.
Control engineering focuses on the modeling of a diverse range of dynamic systems and the design of controllers that will cause these systems to behave in the desired manner. Control engineering has a wide range of applications from the flight and propulsion systems of commercial airliners to the cruise control present in many modern automobiles. Control engineers often utilize feedback when designing control systems. For example, in an automobile with cruise control the vehicle's speed is continuously monitored and fed back to the system which adjusts the motor's power output accordingly.
Where there is regular feedback, control theory can be used to determine how the system responds to such feedback. Electronic engineering involves the design and testing of electronic circuits that use the properties of components such as resistors , capacitors , inductors , diodes , and transistors to achieve a particular functionality. Another example to research is a pneumatic signal conditioner.
Prior to the Second World War, the subject was commonly known as radio engineering and basically was restricted to aspects of communications and radar , commercial radio , and early television. In the mid-to-late s, the term radio engineering gradually gave way to the name electronic engineering. Before the invention of the integrated circuit in ,  electronic circuits were constructed from discrete components that could be manipulated by humans. These discrete circuits consumed much space and power and were limited in speed, although they are still common in some applications.
By contrast, integrated circuits packed a large number—often millions—of tiny electrical components, mainly transistors ,  into a small chip around the size of a coin. This allowed for the powerful computers and other electronic devices we see today. Microelectronics engineering deals with the design and microfabrication of very small electronic circuit components for use in an integrated circuit or sometimes for use on their own as a general electronic component. Nanoelectronics is the further scaling of devices down to nanometer levels. Microelectronic components are created by chemically fabricating wafers of semiconductors such as silicon at higher frequencies, compound semiconductors like gallium arsenide and indium phosphide to obtain the desired transport of electronic charge and control of current.
The field of microelectronics involves a significant amount of chemistry and material science and requires the electronic engineer working in the field to have a very good working knowledge of the effects of quantum mechanics. Signal processing deals with the analysis and manipulation of signals. For analog signals, signal processing may involve the amplification and filtering of audio signals for audio equipment or the modulation and demodulation of signals for telecommunications. For digital signals, signal processing may involve the compression , error detection and error correction of digitally sampled signals.
Signal Processing is a very mathematically oriented and intensive area forming the core of digital signal processing and it is rapidly expanding with new applications in every field of electrical engineering such as communications, control, radar, audio engineering , broadcast engineering , power electronics, and biomedical engineering as many already existing analog systems are replaced with their digital counterparts. Analog signal processing is still important in the design of many control systems.
DSP processor ICs are found in many types of modern electronic devices, such as digital television sets ,  radios, Hi-Fi audio equipment, mobile phones, multimedia players , camcorders and digital cameras, automobile control systems, noise cancelling headphones, digital spectrum analyzers , missile guidance systems, radar systems, and telematics systems.
In such products, DSP may be responsible for noise reduction , speech recognition or synthesis , encoding or decoding digital media, wirelessly transmitting or receiving data, triangulating position using GPS , and other kinds of image processing , video processing , audio processing , and speech processing.
Telecommunications engineering focuses on the transmission of information across a communication channel such as a coax cable , optical fiber or free space. Popular analog modulation techniques include amplitude modulation and frequency modulation. Once the transmission characteristics of a system are determined, telecommunication engineers design the transmitters and receivers needed for such systems. These two are sometimes combined to form a two-way communication device known as a transceiver. A key consideration in the design of transmitters is their power consumption as this is closely related to their signal strength.
Instrumentation engineering deals with the design of devices to measure physical quantities such as pressure , flow , and temperature. For example, flight instruments measure variables such as wind speed and altitude to enable pilots the control of aircraft analytically. Similarly, thermocouples use the Peltier-Seebeck effect to measure the temperature difference between two points. Often instrumentation is not used by itself, but instead as the sensors of larger electrical systems.
For example, a thermocouple might be used to help ensure a furnace's temperature remains constant. Computer engineering deals with the design of computers and computer systems. This may involve the design of new hardware , the design of PDAs , tablets, and supercomputers , or the use of computers to control an industrial plant. However, the design of complex software systems is often the domain of software engineering , which is usually considered a separate discipline.
Mechatronics is an engineering discipline which deals with the convergence of electrical and mechanical systems. Such combined systems are known as electromechanical systems and have widespread adoption. Examples include automated manufacturing systems ,  heating, ventilation and air-conditioning systems ,  and various subsystems of aircraft and automobiles.
The term mechatronics is typically used to refer to macroscopic systems but futurists have predicted the emergence of very small electromechanical devices. Already, such small devices, known as Microelectromechanical systems MEMS , are used in automobiles to tell airbags when to deploy,  in digital projectors to create sharper images, and in inkjet printers to create nozzles for high definition printing. In the future it is hoped the devices will help build tiny implantable medical devices and improve optical communication. Biomedical engineering is another related discipline, concerned with the design of medical equipment.
This includes fixed equipment such as ventilators , MRI scanners ,  and electrocardiograph monitors as well as mobile equipment such as cochlear implants , artificial pacemakers , and artificial hearts. Aerospace engineering and robotics an example is the most recent electric propulsion and ion propulsion. Electrical engineers typically possess an academic degree with a major in electrical engineering, electronics engineering , electrical engineering technology ,  or electrical and electronic engineering.
The bachelor's degree generally includes units covering physics , mathematics , computer science , project management , and a variety of topics in electrical engineering. At some schools, the students can then choose to emphasize one or more subdisciplines towards the end of their courses of study. At many schools, electronic engineering is included as part of an electrical award, sometimes explicitly, such as a Bachelor of Engineering Electrical and Electronic , but in others electrical and electronic engineering are both considered to be sufficiently broad and complex that separate degrees are offered.
The master's and engineer's degrees may consist of either research , coursework or a mixture of the two. The Doctor of Philosophy and Engineering Doctorate degrees consist of a significant research component and are often viewed as the entry point to academia. In the United Kingdom and some other European countries, Master of Engineering is often considered to be an undergraduate degree of slightly longer duration than the Bachelor of Engineering rather than postgraduate. In most countries, a bachelor's degree in engineering represents the first step towards professional certification and the degree program itself is certified by a professional body.
The advantages of licensure vary depending upon location. For example, in the United States and Canada "only a licensed engineer may seal engineering work for public and private clients". Practically all certifying bodies maintain a code of ethics that they expect all members to abide by or risk expulsion. Even in jurisdictions where certification has little or no legal bearing on work, engineers are subject to contract law. In cases where an engineer's work fails he or she may be subject to the tort of negligence and, in extreme cases, the charge of criminal negligence.

In addition, universities will want you to have done physics or chemistry or a technology subject. You can also stand out if you express your interest in the subject by having participated and obtained good results in mathematics and physics challenges. Extra-curricular engineering courses or activities may also help you in the application process.

As they advance in their careers, electrical engineers take on management responsibilities. They sometimes have to take on extra working hours especially by the end period of their projects. Being an electrical engineer may involve both domestic and international travel.
