$A$ $280 \ \Omega$ electric bulb is connected to a $200 \ V$ electric line. The peak value of current in the bulb will be:

The root mean square $(RMS)$ value of the alternating current is equal to:

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

$A$ direct current of $5\,A$ is superposed on an alternating current $I = 10 \sin \omega t$ flowing through a wire. The effective value of the resulting current will be

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:

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 $A$)
