In series LCR circuit, at resonance the peak value of current will be [$$\mathrm{E_0}$$ is peak emf, R is resistance, $$\omega \mathrm{L}$$ is inductive reactance and $$\omega \mathrm{C}$$ is capacitive]

$$\frac{E_0}{R}$$

$$\frac{E_0}{\sqrt{2} R}$$

$$\frac{E_0}{\sqrt{R^2+\left(\omega L-\frac{1}{\omega C}\right)^2}}$$

$$\frac{E_0}{\sqrt{2} \sqrt{R^2+\left(\omega L-\frac{1}{\omega C}\right)^2}}$$
