Q1
If the resistances in a Wheatstone bridge are R1, R2, R3, and R4, what is the condition for balance?
R1/R2 = R3/R4
R1 + R2 = R3 + R4
R1 * R4 = R2 * R3
R1 - R2 = R3 - R4
Show Solution
Copy
The condition for balance in a Wheatstone bridge is R1/R2 = R3/R4.

Q
Q: If the resistances in a Wheatstone bridge are R1, R2, R3, and R4, what is the condition for balance?
Solution:
The condition for balance in a Wheatstone bridge is R1/R2 = R3/R4.
Steps: 5
Show Steps
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.
