electron

What is the difference between electrical and electronic devices? The distinction between electrical and electronic components/ elements is two-fold. The former, like electric wires/ cables, resistors, etc. are passive i.e. they do not require a power supply for operation. Secondly, the output power of the signals applied to them can never exceed the input power i.e. there is no power amplification. Electronic components like valves, transistors, ICs, etc. are active components. They need their own power supply for operation and also, depending on the design, may or may not provide power amplification.
