Study Notes
Wheatstone Bridge
- A Wheatstone bridge is a circuit with four resistors arranged in a diamond shape.
- A voltage source is connected across two opposite corners of the diamond.
- An ammeter is connected across the other two corners.
- The bridge is balanced when there is no current flowing through the ammeter.
- When balanced, the ratio of the resistances on one side of the bridge equals the ratio of the resistances on the other side: R₁/R₂ = R₃/R₄.
- This principle is used to measure unknown resistances.
