In the given circuit, if dt dI = − 1 A / s then the value of ( V A − V B ) at this instance will be

Applying KVL in the given circuit from point A to B , ∴ V AB − IR − L dt dI − 12 = 0 V AB − ( 2 ) ( 12 ) − 6 ( − 1 ) − 12 = 0 V AB = 24 + 12 − 6 V AB = 30 V

In the given circuit, if $\frac{dI}{dt} = - 1 A / s$ then the value of $(V_{A} - V_{B})$ at this instance will be

Options:

Answer:

Solution:

Applying KVL in the given circuit from point $A$ to $B$ , $∴ V_{AB} - IR - L \frac{dI}{dt} - 12 = 0 V_{AB} - (2) (12) - 6 (- 1) - 12 = 0 V_{AB} = 24 + 12 - 6 V_{AB} = 30 V$
