Q69 / 90 · JEE Main 2024 (04 Apr Shift 1) · Physics

The value of net resistance of the network as shown in the given figure is :

Correct answer
A
$6 \Omega$
B
$(5 / 2) \Omega$
C
$(15 / 4) \Omega$
D
$(30 / 11) \Omega$

Solution

Diode 2 is in reverse bias So current will not flow in branch of $2^{\text {nd }}$ diode, So we can assume it to be broken wire. Diode 1 is in forward bias So it will behave like conducting wire. So new circuit will be

Hence, the correct answer is option: 'A'.
