MCQ
The diode shown in the circuit is a silicon diode. The potential difference between the points $A$ and $B$ will be.....$V$
  • $6$
  • B
    $0.6$
  • C
    $0.7$
  • D
    $0$

Answer

Correct option: A.
$6$
a
(a)In the given condition diode is in reverse biasing so it acts as open circuit. Hence potential difference between $A$ and $B$ is $ 6V$
