Q: If the resistance R1 is increased in a Wheatstone bridge, what happens to the balance condition?

Solution: Increasing R1 will disturb the balance unless R2 is also adjusted accordingly.

Steps: 6

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: R1, R2, R3, and R4.
Step 3: Know the balance condition. The bridge is balanced when the ratio of R1 to R2 is equal to the ratio of R3 to R4 (R1/R2 = R3/R4).
Step 4: Consider what happens when R1 is increased. If R1 increases, the ratio R1/R2 changes unless R2 is also changed.
Step 5: Realize that if R2 is not adjusted, the balance condition will be disturbed. This means the bridge will no longer be balanced.
Step 6: Conclude that to maintain balance after increasing R1, R2 must be adjusted accordingly.
