The equilvalent resistance and potential difference between A and B for the circuit respectively are

Options

  1. A4 , 8 ~V
  2. B8 , 4 ~V
  3. C2 , 2 ~V
  4. D16 , 8 ~V

Correct answer

A. 4 , 8 ~V

Step-by-step solution

The equivalent resistance between A and B is 1 R^ = 1 6 + 1 6 + 1 3 = 2 3 or R^ = 3 2 =1.5 Now the equivalent resistance between A and B is R^ =1.5+2.5=4 Now by Ohm's law, potential difference between A and B is given by aligned V_A-V_B & =i R=2 4.0 & =8 volt aligned
