A semiconductor device $X$ is connected in series with a battery and a resistor. The current of 10 mA is found to pass through the circuit. If the terminals of X are connected in reverse manner, the current drops to almost zero. $X$ may be
a zener diode
a p-n junction diode
an intrinsic semiconductor
an extrinsic semiconductor
Solution
In a p-n junction diode, a very small, nearly zero current flows through the junction when it is reverse biased.
