Question

Please help me i. please solve q . 7 in brief with whole solution.

Answer 1

1. Both s1 and s2 are closed. In this case, total current of the circuit will flow through branch FG and branch HI will not conduct any current. Hence, the current will flow only through resistances R1,R2and R3 and it will not flow through R4 . 2. Both S1 and S2 are open. In this case, current will flow through resistances R1, R3, and R4. However since the branch DE is open, it will Not flow through R2. 3. S1 is closed but S2 is open. In this case, current will flow through resistances R1, R2, R3 and R4.
