The condition for resonance is:ωC1​=ωL The peak current through the circuit is given by,i0​=R2+(ΔC1​−ωL)​2V0​​ From the condition of resonance, we get:i0​=RV0​​ The current will flow through the all circuit elements. But since the reactance of the capacitor and inductor are equal, the potential difference across them will be equal and opposite and will cancel each other.
