Question
Figure shows a balanced Wheastone′s bridge
Options
A.If P is slightly increased, the current in the galvanometer flows from C to A
B.If P is slightly increased, the current in the galvanometer flows from A to C
C.If Q is slightly increased, the current in the galvanometer flows from C to A
D.If Q is slightly increased, the current in the galvanometer flows from A to C
Solution
If P is slightly increased potential of C will decrease. Hence current will from A to C. If Q is slightly increased, potential of C will increase, hence current will flow from C to A
