A ( 100 ~W ) bulb is connected to an ( AC ) source of ( 220 ~V , 50 ~Hz ). Then the current flowing through the bulb is

Options

  1. A( 5 11 A )
  2. B( 1 2 A )
  3. C( 2 ~A )
  4. D( 3 4 A )

Correct answer

A. ( 5 11 A )

Step-by-step solution

Given, power of bulb ( =100 ~W ); voltage of source ( =200 ~V ) Now, ( P=I V I= P V = 100 220 = 5 11 A ) Therefore, current flowing through the bulb is ( 5 11 A )
