Q1:

The electrical energy consumed by a coil is stored in the form of:

A an electrical field

B a force field

C an electrostatic field

D a magnetic field

ANS:D - a magnetic field

Coil: Short for electromagnetic coil, a coil is conducting wire such as copper shaped in a helical form around an iron core.

The coil creates an inductor or electromagnet to store magnetic energy.
