Question: If the resistances in a Wheatstone bridge are R1, R2, R3, and R4, what is the condition for balance?

Options:

Correct Answer: R1/R2 = R3/R4

Solution:

The condition for balance in a Wheatstone bridge is R1/R2 = R3/R4.

If the resistances in a Wheatstone bridge are R1, R2, R3, and R4, what is the condition for balance?

Correct Answer: R1/R2 = R3/R4

Step 1: Understand that a Wheatstone bridge has four resistors: R1, R2, R3, and R4.
Step 2: Recognize that the bridge is balanced when the ratio of the resistances in one branch equals the ratio in the other branch.
Step 3: Write down the ratios: R1 is in one branch with R2, and R3 is in the other branch with R4.
Step 4: Set up the equation for balance: R1 divided by R2 should equal R3 divided by R4.
Step 5: Conclude that the condition for balance is R1/R2 = R3/R4.

Wheatstone Bridge Balance Condition – The Wheatstone bridge is a circuit used to measure unknown resistances by balancing two legs of a bridge circuit. The condition for balance is that the ratio of the resistances in one leg equals the ratio in the other leg.
