At resonance, the value of current in a series L-C-R- (Symbols have their usual meanings.)

Options

  1. Ae ₀ R
  2. Be ₀ r ^2+ ^2 C ^2
  3. Ce ₀ [ R ^2+ ( L + 1 C )^2 ]
  4. De ₀ R ^2+ ^2 ~L ^2

Correct answer

A. e ₀ R

Step-by-step solution

At resonance, L = 1 C So, i = e ₀ R ^2+ ( L - 1 C )^2 = e ₀ R ^2 = e ₀ R
