Q: If the galvanometer in a Wheatstone bridge has a resistance of 5Ω and the bridge is balanced, what is the current through the galvanometer?

Solution: In a balanced Wheatstone bridge, the current through the galvanometer is zero.

Steps: 6

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances.
Step 2: Know that a galvanometer is an instrument used to detect and measure small electric currents.
Step 3: Recognize that a balanced Wheatstone bridge means that the ratio of the resistances in one branch is equal to the ratio in the other branch.
Step 4: In a balanced Wheatstone bridge, the potential difference across the galvanometer is zero.
Step 5: Since the potential difference is zero, there is no current flowing through the galvanometer.
Step 6: Therefore, the current through the galvanometer is zero.
