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
diode is short circuited
diode is open circuited
resistor is open circuited
diode is either short circuited or open circuited
Correct Answer:
diode is open circuited
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.
