Question

Charge and voltage associated with electric field are analogous, respectively to __________ and ___________ in magnetic field.

(a) flux linkages and current

(b) flux density and current

(c) flux linkages and voltage

(d) MMF and current

I had been asked this question in an online interview.

The origin of the question is Singly Excited Electric Field Systems topic in portion Basic Concepts in Rotating Machines of Electrical Machines

Answer 1

Right option is (a) flux linkages and current

To explain I would say: In magnetic field, the basic terms are flux linkages and current, which are responsible for energy conversion and in electric field, charge and voltage are basically responsible for energy conversion.

dWelec = ψi, for magnetic field

dWelec = vidt=vdq, for electric field.
