When an A C source of emf E with frequency =100 ~Hz is connected across a circuit, the phase difference between E and current I in the circuit is observed to be 4 as shown in the figure. If the circuit consist of only RC or RL in series, then

Options

  1. AR =1 k , C =5 F
  2. BR =1 k , L =10 H
  3. CR =1 k , L =1 H
  4. DR =1 k , C =10 F

Correct answer

D. R =1 k , C =10 F

Step-by-step solution

.. Since supply voltage lags the current By ( = / 4) aligned & = X _ C R =1, X _ C = R (1) & X _ C = 1 C = 1 100 10 10⁻⁶ =1 k = R aligned
