As per the given figure, if d I d t = - 1   A   s - 1 , then the value of V AB at this instant will be ______ V .

Correct answer

0

Step-by-step solution

Given here, d I d t = - 1   A   s - 1 Applying Kirchhoff's voltage law to the circuit, V A - I R - L d I d t - 12 = V B ⇒ V A - 2 × 12 - 6 ( - 1 ) - 12 = V B ⇒ V A B = V A - V B = 36 - 6 = 30   V
