Effective resistance between ( A ) and ( B ) in the following circuit

Options

  1. A( 10 )
  2. B( ( 20 )
  3. C( 5 )
  4. D( 20 3 )

Correct answer

A. ( 10 )

Step-by-step solution

Equivalent circuit of the given circuit is shown above which is a balanced Wheat stone bridge i.e. ( 10 10 = 10 10 ) Equivalent resistance between ( A ) and ( B , R _ eq =(10+10) |(10+10)=20 | 20 ) ( R _ eq = 20 20 20+20 =10 )
