Which of the following components of a $LCR$ circuit, with $ac$ supply, dissipates energy
$L$
$R$
$C$
All of these
In an ac circuit, peak value of voltage is $423\, volts$. Its effective voltage is .......... $volts$
The root mean square value of the alternating current is equal to
For the $RC$ circuit shown, the resistance is $R = 10.0\ W$, the capacitance is $C = 5.0\ F$ and the battery has voltage $\xi= 12$ volts . The capacitor is initially uncharged when the switch $S$ is closed at time $t = 0$. At some time later, the current in the circuit is $0.50\ A$. What is the magnitude of the charge across the capacitor at that moment?.......$µC$
Find the time required for $50\,Hz$ alternating current to change its value from zero to maximum value.
Explain electrical energy when an ac current passes through a resistor.
