MCQ
What is the current in the circuit shown below.....$amp$
- ✓$0$
- B${10^{ - 2}}$
- C$1$
- D$0.10 $
✓
Answer
Correct option: A.
$0$
a
(a) The potential of $P-$side is more negative that of $N-$side, hence diode is in reverse biasing. In reverse biasing it acts as open circuit, hence no current flows.
