Questions & Step-by-Step Solutions
In a Wheatstone bridge, if the battery voltage is increased, what happens to the balance condition?
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, R4) and a battery.
Step 3: Know the balance condition. The bridge is balanced when the ratio of the resistances in one leg equals the ratio in the other leg: R1/R2 = R3/R4.
Step 4: Recognize that the balance condition is based on the ratios of the resistances, not the voltage from the battery.
Step 5: Conclude that if the battery voltage is increased, it does not affect the balance condition because the ratios of the resistances remain the same.
