PDF EXPERIMENT 10 THE WHEATSTONE BRIDGE
The Wheatstone Bridge is an instrument designed for measuring an unknown resistance by comparing it with a known, or standard, resistor. In the schematic diagram in section IV, R1 is an unknown resistor whose value is to be determined. Three known resistors are required, as well as a galvanometer and a cell (battery).
Wheatstone Bridge Circuit and Theory of Operation
The Wheatstone Bridge diamond shaped circuit who's concept was developed by Charles Wheatstone can be used to accurately measure unknown resistance values, or as a means of calibrating measuring instruments, voltmeters, ammeters, etc, by the use of a variable resistance and a simple mathematical formula.. Although today digital multimeters provide the simplest way to measure a resistance.
Wheatstone Bridge Circuit
A Wheatstone bridge consists of four resistors (R 1, R 2, R 3 and R 4) that are connected in the shape of a diamond with the DC supply source connected across the top and bottom points (C and D in the circuit) of the diamond and the output is taken across the other two ends (A and B in the circuit).
Wheatstone Bridge
The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistances is equal, and no current flows through the circuit. Under normal conditions, the bridge is in an unbalanced condition where current flows through the galvanometer. The bridge is said to be balanced when no current flows through the galvanometer.
