Question:

The frequencies of a.c. generator depends on:

Options:

amplitude of a.c.

size of the coil

speed of the rotation of the coil

wavelength of a.c.

Correct Answer:

speed of the rotation of the coil

Explanation:

The correct answer is Option (3) → speed of the rotation of the coil

The frequency (v) of the generated A.C. is -

$v=\frac{N.Rotational\, speed}{360}$

Thus, the frequency depend directly on the rotational speed of the coil.
