Question
Name and state the principle of a simple a.c. generator. What is its use?

Solution
An A.C. generator works on the principle of 'electromagnetic induction'.
Statement: Whenever a coil is rotated in a magnetic field, the magnetic flux linked with the coil changes, and therefore, an EMF is induced between the ends of the coil. Thus, a generator acts like a source of current if an external circuit containing load is connected between the ends of its coil.
