Q. In n-channel enhancement MOSFET, at a fixed drain voltage
Option
a) the drain current is maximum at zero gate voltage and it decreases with applied negative gate voltage
b) the drain current has a finite value at zero gate voltage and it increases or decreases with the applied voltage of proper polarity
c) the drain current is zero at zero gate voltage and it increases with the positive applied gate voltage
d) the drain current is zero for negative bias voltage to gate and it increases as negativegate bias is decreased in magnitude
