In a choke coil,the reactance $X_L$ and resistance $R$ are such that

If we decrease the frequency of the applied $A.C.$ with a purely capacitive load,do $(1)$ the amplitude of $V_c$ and $(2)$ amplitude of $I_c$ increase,decrease,or remain the same?

$A$ parallel plate capacitor having plates of radius $6 \text{ cm}$ has capacitance $100 \text{ pF}$. It is connected to a $230 \text{ V}$ a.c. supply with angular frequency $300 \text{ rad/s}$. The r.m.s. value of current is:

$A$ constant voltage at different frequencies is applied across a capacitance $C$ as shown in the figure. Which of the following graphs correctly depicts the variation of current with frequency?
