An alternating voltage is represented by $V = 80 \sin(100 \pi t) \cos(100 \pi t) \text{ V}$. The peak voltage is (in $\text{ V}$)

The average value of alternating current $I = I_0 \sin \omega t$ in the time interval $[0, \frac{\pi}{\omega}]$ is:

In an $AC$ circuit,when an $AC$ ammeter is connected,it reads $i$ current. If a student uses a $DC$ ammeter in place of the $AC$ ammeter,the reading in the $DC$ ammeter will be:

What are $A.C.$ signals?

What is the maximum voltage of $220\, V$ (in $, V$)?

An alternating current is given by the equation $i = i_{1} \sin \omega t + i_{2} \cos \omega t$. The rms current will be
