Answer:

$v = 12sin400\pi t$

Given:

Voltage,
v_(m) = 12 V

frequency, f = 200 Hz

Solution:

The expression for output voltage of an AC source is given by:

$v = v_(m)sin\omega t$

where

$\omega = 2\pi f$

Therefore,

$v = v_(m)sin2\pi f t$

Now, using the given values in the output voltage expression for an ac source:

$v = 12sin2\pi * 200$

Thus the expression so formed is:

$v = 12sin400\pi t$
