Which of the following components of an $LCR$ circuit,with $ac$ supply,dissipates energy?

What is the average power dissipation in an ideal capacitor in an $AC$ circuit?

The same current is flowing in two alternating circuits. The first circuit contains only an inductor and the other contains only a capacitor. If the frequency of the alternating e.m.f. is increased,the values of current will

When an inductor is connected to an $AC$ source of frequency $\omega$,what is the frequency of the instantaneous power?

The reactance of a coil when used in the domestic $AC$ power supply $(220 \, V, 50 \, Hz)$ is $50 \, \Omega$. The inductance of the coil is nearly: (in $H$)

In an $AC$ circuit containing only a capacitor,how does the current relate to the potential difference?
