Electrical and Electronics
Electrical
Electrical is the
branch of science that deals with the flow of electrons in a conductor and the
objects made by the conductor (eg motors, generators, transformers, switchgear,
magnetic contactors, circuit breakers, etc.). In other words, the source of current flow,
electrical circuit, and AC are discussed in the electrical section.
Electronics
Electronics is the
branch of science where charge flows through a semiconductor and conducts
objects made of semiconductors (such as electronic tubes, vacuum tubes, diodes,
transistors, MOSFETs, etc.). CR, Integrated Circuit (IC), Amplifier,
Oscillator, Flipflop, Logicgate, Microcontroller etc.) are discussed. In the
electronics part, work is done with DC.
The main difference
between electrical and electronics circuits is that electrical circuits have no
decision (processing) power, but electronics circuits have decision making
(processing) or control. Most modern appliances use a combination of electrical
and electronics circuits. Basically, this is why electrical and electronics
engineering is coming.
Comparison of electrical and electronics
- Electrical devices convert electrical current into other forms such as heat energy, light energy, etc. Electronics devices control the movement of electrons for various operations.
- Copper or aluminum is used to conduct electric current in electrical devices whereas semiconductor material is used in electronics devices.
- Electrical devices operate primarily on alternating current, while electronic devices operate on DC voltage.
- Electrical devices operate at high voltages whereas electronic devices operate at low voltages.
- The power consumption of electrical devices is much higher than that of electronic devices.
- The conductivity of electrical devices is much higher than that of electronics devices.
- Electrical devices are more dangerous than electronic devices. Faults in electrical devices cause many large short circuits which are very dangerous.
- Examples of electrical devices like fans, transformers, motors, generators, etc. whereas transistors, thyristors, micro-controllers etc. are examples of electronics devices.
