A forward voltage of 9 V is applied to a diode in series with a 1 kΩ load resistor. The voltage across load resistor is zero. It indicates that

[A].	diode is short circuited
[B].	diode is open circuited
[C].	resistor is open circuited
[D].	diode is either short circuited or open circuited

Answer: Option B

Explanation:

Since load voltage is zero, the current is zero and diode is open-circuited. If load was open-circuited, load voltage would be about 9 V.
