Draw the phasor diagram of a purely capacitive circuit.

In a circuit consisting of a capacitance and a generator with alternating emf, $E_g=E_{go}sin\omega t, V_C$ and $I_{\mathit{C}}$ are the voltage and current. Correct phasor diagram for such circuit is

In the given circuit the $\mathrm{AC}$ source has $\omega =100 \mathrm{rad} {\mathrm{s}}^{-1}$. Considering the inductor and capacitor to be ideal, what will be the current $I$ flowing through the circuit?

A capacitor of capacitance $0.5 \mathrm{\mu F}$ is connected to a source of alternating e.m.f. of frequency $100 \mathrm{Hz}$. What is the capacitive reactance? $(\pi = 3.142)$

A light bulb and an open coil inductor are connected to an ac source through a key as shown in figure. The switch is closed and after sometime, an iron rod is inserted into the interior of the inductor. What will be effect on glow of light bulb while inserting the rod. Give your answer with reason.

A parallel combination of pure inductor and capacitor is connected across a source of alternating EMF $e$. The currents flowing through an inductor and capacitor are $i_L$ and $i_C$ respectively. In this parallel resonant circuit, the condition for currents $i$ $,i_L$ and $i_C$ is ($i=$net RMS current in the circuit)
