Electronic – How is a current controlled voltage source different from a resistor


A current controlled voltage source produces a voltage that is linearly proportional to a current. A resistor has the same behavior. And the gain for a CCVS is measured in ohms, which is the same unit that measures a resistor. So what is the difference between them? Is a resistor just a kind of CCVS (and I guess also a VCCS) and if so, how does it differ from an ideal CCVS?

A resistor is a passive component. A current controlled voltage source is an active component i.e. the voltage will remain proportional to the current controlling it regardless of what else is connected to the source (ideally).
