Assertion: When Wheatstone bridge is balanced, the current through the cell depends on the resistance of galvanometer.
Reason: In the balanced condition, current through the galvanometer is very high.
Reason: In the balanced condition, current through the galvanometer is very high.
View answer and explanation
Correct option: D
If both Assertion & Reason are False
Option D (If both Assertion & Reason are False) is correct because in a balanced Wheatstone bridge, the current through the galvanometer is zero, and the current through the cell depends on the overall resistance of the bridge, not the galvanometer's resistance.
