Solution

Q.
As per the given figure, if $\frac{d I}{d t} = - 1 A/s$ then the value of $V_{A B}$ at this instant will be _______ V. [2023]

Ans.
(30)

$\frac{d I}{d t} = - I \frac{A}{\sec}$

$V_{A} - I R - L \frac{d I}{d t} - 12 = V_{B}$

$V_{A} - 2 \times 12 - 6 (- 1) - 12 = V_{B}$

$V_{A} - V_{B} = 36 - 6 = 30 V$
