With the gradual increase in frequency of an a. c. source, the impedance of an LCR series circuit

Options

  1. Afirst decreases, becomes minimum and then increases.
  2. Bincreases.
  3. Cdecreases.
  4. Dremains constant.

Correct answer

A. first decreases, becomes minimum and then increases.

Step-by-step solution

With increase in frequency current increases initially, becomes maximum and then decreases with further increase in frequency.
