The readings of ammeter and voltmeter in the following circuit are respectively

Options

  1. A( ( 2.7 ~A , 220 ~V )
  2. B( 1.2 ~A , 120 ~V )
  3. CO ( 2.2 ~A , 220 ~V )
  4. D( 1.5 ~A , 100 ~V )

Correct answer

C. O ( 2.2 ~A , 220 ~V )

Step-by-step solution

(C) ( V_ L =V_ C ) it is a resistive circuit ( V =220 ~V ) and ( I= V R = 220 100 =2.2 ~A )
