Application +4 | -1

Write the equation of a sinusoidal voltage of rms valus

220 \mathrm{~V}

and frequency

50 \mathrm{~Hz}

View answer and explanation

Correct option: B

220 \sqrt{2} \sin (100 \pi t)

Option B is correct. The equation for a sinusoidal voltage is

V = V_0 \sin(2 \pi f t)

, where

V_0 = V_{rms} \sqrt{2}

and

f

is the frequency.
