When some potential difference is maintained between A and B, current I enters the network at A and leaves at B see figure. (a) The equivalent resistance between A and B is (8 ) (b) C and D are at the same potential. (c) No current flows between C and D (d) Current (3 I / 5 ) flows from D to C.

Options

  1. Aa, b, d are correct
  2. Ba, d are correct
  3. Ca, c, d are correct
  4. Dall are correct

Correct answer

A. a, b, d are correct

Step-by-step solution

( aligned & I^ = 5 25 I= I 5 R_ e q =4+4=8 & I^ = 20 25 I= 4 I 5 Also =V_C=V_D & Current in D C= 4 I 5 - I 5 =3 I / 5 aligned )
