The Wheatstone bridge is a circuit used for measuring electrical resistance with high accuracy. It was invented by Samuel Hunter Christie in 1833 and popularized by Sir Charles Wheatstone in 1843.
Principle of Wheatstone Bridge
The Wheatstone bridge consists of four resistors connected in a diamond shape with a voltage source. It operates on the principle of null deflection, where the bridge is balanced when there is no current flow through the center galvanometer.
How Does It Work?
When a voltage is applied to the input terminals of the Wheatstone bridge, the bridge is adjusted by varying one of the resistors until the galvanometer shows zero deflection. At this point, the ratio of the resistors is known, allowing for the determination of an unknown resistance.
Applications of Wheatstone Bridge
The Wheatstone bridge is widely used in various fields, including electronics, physics, and engineering. It is commonly employed in strain gauge measurements, temperature sensors, and resistance measurements.
Accuracy and precision are key attributes of the Wheatstone bridge, making it a preferred choice for applications requiring reliable resistance measurements. Its balanced design ensures minimal error in readings.
Overall, the Wheatstone bridge is a fundamental circuit in electrical measurements, offering a robust and efficient method for determining unknown resistances with high accuracy and precision.
