Using KVL with I = 2 A, R = 12 Ω, L = 6 H and battery 12 V: the resistor drop is IR = 24 V and inductor voltage magnitude is L|dI/dt| = 6 V. With the indicated polarities, V(A)-V(B) = 24 + 12 - 6 = 30 V.

As per the given figure, if dI/dt = -1 A s⁻¹, then the value of V A B V_{AB} V A B ​ at this instant will b e _____ V.
