Wheatstone Bridge Formula
The Wheatstone Bridge Formula for the calculation of the unknown resistor is as follows:
R = PS/Q
where,
P and Q is the resistance of ratio arm
S is the known resistance of the standard arm
R is the unknown resistance
Wheatstone Bridge
Wheatstone bridge is a device that is used to find the resistance of a conductor, in 1842, scientist Wheatstone proposed a theory, which is called the principle of Wheatstone bridge after his name. we can prove or establish the formula for Wheatstone by using Kirchhoff laws. Wheatstone bridge is simply an electric circuit used to measure an unknown electric resistance by balancing two-point of a bridge. Let’s get started!
