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

The alternating voltage is given by $v=v_0 \sin \left(\omega t+\frac{\pi}{3}\right)$. When will the voltage be maximum for the first time?

The output of a step-down transformer is measured to be $24 \ V$,when connected to a $12 \ W$ light bulb. The value of peak current is $...... \ A$. (in $A$)

The instantaneous values of current and emf in an $AC$ circuit are $I = 1/\sqrt{2} \sin(314t) \, A$ and $E = \sqrt{2} \sin(314t - \pi/6) \, V$ respectively. The phase difference between $E$ and $I$ will be

The frequency of an alternating current is $ 50 \,Hz $. What is the minimum time taken by the current to reach its peak value from its $ rms $ value?

In India,$AC$ voltage becomes zero how many times in $1$ $sec$?
