Despite the fact that both electrical and electronic instruments measure electrical quantities like voltage and current, they differ from each other in terms of the built-in features; for example, purely electrical instruments don’t possess any in-built amplifying device to increase the amplitude of the quantity being measured whereas electronic instruments typically incorporate an amplifier. DC voltmeter that is based on moving-coil meter movement is a good example of an electrical instrument.
Electronic instruments often include in their structure some active electron device such as a semiconductor diode or an integrated circuit (IC), etc. This is not true for electrical instruments.

Even though the key distinguishing factor between the two types of instruments is the presence of an electron device in the electronic instruments, both are characterized by movement of electrons, the main difference being that the control of electron movement is more effective in electronic instruments than in electrical instruments.
While electronic instruments are typically more expensive than their electrical counterparts, they offer the following advantages for measurement purposes:
