If the current changes from 3A to 5A in 2s and the emf is 10V. Calculate the inductance.

(a) 10H

(b) 20H

(c) 30H

(d) 40H

The question was posed to me in unit test.

This intriguing question comes from Inductance in Terms of Flux Linkages Per Ampere topic in portion Inductance in a DC Circuit of Basic Electrical Engineering
