There are only two variables in any electrical circuit, the primary (or independent) one is voltage, and the secondary (or dependent) one is current. It is voltage which drives the current through whatever passive device is attached to the circuit, whether it be resistance, capacitance or inductance. Again it is voltage which excites active devices (semiconductors etc), whether they be voltage or current driven.
But what would be an example of something current driven?
QuoteBut what would be an example of something current driven?A ordinary NPN or PNP is current driven, but a FET is voltage driven.
