Which of the following statements is true regarding a balanced Wheatstone bridge?

Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown electrical resistances.
Step 2: Know that a Wheatstone bridge has four resistors arranged in a diamond shape.
Step 3: Identify the two pairs of resistors in the bridge. One pair is on the left side and the other pair is on the right side.
Step 4: Learn that a galvanometer is connected between the two midpoints of the resistors.
Step 5: Recognize that a balanced Wheatstone bridge means the ratio of the resistances in one pair is equal to the ratio in the other pair.
Step 6: When the bridge is balanced, the voltage (potential difference) across the galvanometer is zero.
Step 7: Conclude that since there is no voltage across the galvanometer, no current flows through it.
