Peak Current in LCRHardQuestion 20220

Question

A series LCR circuit (R=10 Ω, Z=50 Ω) is connected to a 100 V RMS AC source. Peak current I₀ is:
  1. A
    2 A
  2. B
    2√2 A
    Correct
  3. C
    10 A
  4. D
    1 A

Correct answer

2√2 A

Explanation

I_rms = V_rms/Z = 100/50 = 2 A. Peak current I₀ = I_rms × √2 = 2√2 A.
