In LCR series circuit with resistance R. inductive reactance $X_L$ and capacitive reactance $X_C$, the maximum current '$I_0$' at resonance is given as:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $I_0=\frac{V_0}{R}$
The maximum current $(I_0)$ occurs when the impedance is at its minimum, which is simply R.
$∴I_0=\frac{V_0}{R}$
