Q1
What is the condition for a Wheatstone bridge to be balanced?
R1/R2 = R3/R4
R1 + R2 = R3 + R4
R1 - R2 = R3 - R4
R1 * R2 = R3 * R4
Show Solution

Q: What is the condition for a Wheatstone bridge to be balanced?
Solution:
The condition for a Wheatstone bridge to be balanced is R1/R2 = R3/R4.
Steps: 5
Show Steps
Step 1: Understand that a Wheatstone bridge is a circuit used to measure unknown resistances.
Step 2: Identify the four resistors in the Wheatstone bridge: R1, R2, R3, and R4.
Step 3: Recognize that the bridge is balanced when there is no current flowing through the middle part of the circuit.
Step 4: Know that the condition for balance is when the ratio of the resistors is equal: R1 divided by R2 should equal R3 divided by R4.
Step 5: Write the condition mathematically as R1/R2 = R3/R4.
