Current Electricity 2 Question 16
16. In the circuit shown $P \neq R$, the reading of galvanometer is same with switch $S$ open or closed. Then
(1999, 2M)
(a) $I _R=I _G$
(b) $I _P=I _G$
(c) $I _Q=I _G$
(d) $I _Q=I _R$
Show Answer
Solution:
- As there is no change in the reading of galvanometer with switch $S$ open or closed. It implies that bridge is balanced. Current through $S$ is zero and $I _R=I _G, I _P=I _Q$.
