At an instant when the current through an inductor is I = 4.0 A and the current through the inductor is increasing at a rate of Δi/Δt = +0.50 A/s, the voltage across the inductor is 8.0 V. The resistance of the inductor is negligible. What is the self-inductance of the inductor?

(a) 2.0 H

(b) 32.0 H

(c) 16.0 H

(d) 8.0 H

(e) 4.0 H

(f) none of these answers
