Q
Q: In a Wheatstone bridge, if the battery voltage is 12V 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: 4
Show Steps
Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances by balancing two legs of a bridge circuit.
Step 2: Know that a balanced Wheatstone bridge means that the ratio of the resistances in one leg is equal to the ratio in the other leg.
Step 3: Recognize that when the bridge is balanced, there is no potential difference across the galvanometer.
Step 4: Since there is no potential difference, the current through the galvanometer is zero.
