Interview Question:

What is the main difference between electrical& electronics? Define them.


In Electronics, as we study about the motion of electrons in the semi conducting materials, the currents and voltages are of very negligible values. With the less amounts of current and voltages we are able to perform many tasks using Electronics.

Where as in electrical, it is the study of motion of electrons  in metals.So, usually the conductivity is more for metals, so more voltage of order 230v and more currents of higher order amps are used.
