VA-VB=VL+VR=(d l/d t)+I R or 0.5=L × 8+0.5 × 0.2 L=0.05 H

Q. In the given sub circuit, the resistance $R = 0.2 Ω$ . If $(V_{A} - V_{B}) = 0.5 V, I = 0.5 A$ and $(d I / d t) = 8 A / s$ , then find the inductance of the coil.

0.01 H

0.02 H

0.05 H

0.5 H

$V_{A} - V_{B} = V_{L} + V_{R} = \frac{d l}{d t} + I R$
or $0.5 = L \times 8 + 0.5 \times 0.2$
$L = 0.05 H$
