Question

The equation of an alternating voltage is V =100 sin 100 $\pi$ t volt. Its peak value and frequency are

• A. 100 V, 50 Hz
• B. 50V, 100Hz
• C. 200 V, 100 Hz
• D. 100 V, 200 Hz

Answer 1

The correct option is A 100 V, 50 Hz

V = 100 sin 10 $\pi$ t
$V_0$ = 100 v; $\omega$ = 100 $\pi$ = 2 $\pi$ n
n = 50 Hz
