Question

Regarding self-inductance:\ A. The self-inductance of the coil depends on its geometry.\ B. Self-inductance does not depend on the permeability of the medium.\ C. Self-induced e.m.f. opposes any change in the current in a circuit.\ D. Self-inductance is electromagnetic analogue of mass in mechanics.\ E. Work needs to be done against self-induced e.m.f. in establishing the current.\ Choose the correct answer from the options given below.\
