When VA < VB the diode gets reverse biased and offers infinite resistance. No current flows through the upper branch ∴ R = 20 Ω

Q. The equivalent resistance of the circuit shown in figure between the points $A$ and $B$ if $V_{A} < V_{B}$ is

$10 Ω$

$20 Ω$

$5 Ω$

$40 Ω$

When $V_{A} < V_{B}$ the diode gets reverse biased and offers infinite resistance. No current flows through the upper branch
$∴ R = 20 Ω$
