Out of the following graphs,which graph shows the correct relation (graphical representation) for an $LC$ parallel resonant circuit?

The current in resistance $R$ at resonance is

$A$ resistor of $100 \Omega$,an inductor of self-inductance $(\frac{4}{\pi^2}) \text{ H}$,and a capacitor of unknown capacitance are connected in series to an $A$.$C$. source of $200 \text{ V}, 50 \text{ Hz}$. When the current and voltage are in phase,the capacitance and the power dissipated are respectively:

In an $LCR$ circuit at resonance, the $a.c.$ source current is

On which factor does the sharpness of resonance depend?

If the frequency of the $AC$ supply is equal to the resonant frequency,which ammeter will show zero reading?
