Q. A generator produces a voltage that is given by V=240 sin 120t V, where t is in second. The frequency and r.m.s. voltage are

Alternating Current

Solution:

V = V$_{m}$ sin $\omega$t compare to given equation, we get
$V_m$ =240 and $\omega=120$
$f=\frac{\omega}{2\pi}=\frac{120}{6.28}=19H_z\,$ and
voltage = $\frac{V_m}{\sqrt{2}}=\frac{240}{\sqrt{2}}=170V$
