Calculate the emf induced in an inductor if the inductance is 10H and the current is 2A in 4s.
(a) 2.5V
(b) 1.5V
(c) 3.5V
(d) 5V
The question was posed to me in an interview for internship.
My query is from Energy Stored in an Inductor topic in chapter Inductance in a DC Circuit of Basic Electrical Engineering
