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.
