Q: If the resistance in one arm of a Wheatstone bridge is increased, what happens to the balance condition?

Solution: Increasing the resistance in one arm will disturb the balance condition, making it unbalanced.

Steps: 5

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: Identify the components of the Wheatstone bridge. It has four resistors arranged in a diamond shape with a voltage source and a galvanometer.
Step 3: Know the balance condition. The bridge is balanced when the ratio of the resistances in one arm is equal to the ratio in the other arm.
Step 4: Recognize what happens when you increase the resistance in one arm. This changes the ratio of resistances in that arm.
Step 5: Conclude that increasing the resistance in one arm disturbs the balance condition, making the bridge unbalanced.
