RE: FET Voltage Control Device

Since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain so it is known as voltage controlled device.

For example: In a MOSFET the current from drain to source depends upon the width of the depletion layer which in turn depends upon the voltage applied on the gate so that is the reason.
