Answer» Correct ANSWER is (c) 0mA Best explanation: We know that for a FET, the gate terminal is heavily doped with an insulator, resulting in INFINITE RESISTANCE. Hence no current flows through the gate terminal. It has no relationship with the other current parameters. It is constant for all FETS.
