An alternating voltage is applied to a series LCR circuit. If the current leads the voltage by 45^ , then ( 45^ =1 )

Options

  1. AX_L=X_C-R
  2. BX_L=X_C+R
  3. CX_C= X_L^2+R^2
  4. DX _ L = X _ C ^2+ R ^2

Correct answer

B. X_L=X_C+R

Step-by-step solution

The phase between the voltage and the current is given as array ll & = X_L-X_C R & 45^ = X_L-X_C R & 1= X_L-X_C R & R=X_L-X_C & X_L=X_C+R array
