In series LCR circuit, at resonance the peak value of current will be [E₀ . is peak emf, R is resistance, L is inductive reactance, and 1 / C is capacitive reactance]

Options

  1. AE₀ R
  2. BE₀ 2 R
  3. CE₀ R^2+ ( L- 1 C )^2
  4. DE₀ 2 R^2+ ( L- 1 C )^2

Correct answer

A. E₀ R

Step-by-step solution

At resonance, the net reactance of the circuit is zero and the impedance is equal to the resistance. I ₀= E ₀ R
