An alternating voltage of 22 ~V is applied across an inductance coil of reactance 11 . If the inductance of the coil is 0.07 H , the frequency of alternating voltage is

Options

  1. A25 ~Hz
  2. B40 ~Hz
  3. C50 ~Hz
  4. D20 ~Hz

Correct answer

A. 25 ~Hz

Step-by-step solution

The inductive reactance is aligned & X_L= L & =2 f & 2 f L=X_L & f= X_L 2 L = 11 2 (0.07) Hz =25 ~Hz aligned
