Basics of Wheatstone Bridge

This post was originally published on this site

Wheatstone bridge is a special circuit consisting of 5 resistors. When the resistances in the adjacent arms have the same ratio, no current flows through the middle resistor! This is called a balanced Wheatstone bridge. It’s used in calculating unknown resistances using a meter-bridge set up.

In this video, the presenter will be explaining the basics of Wheatstone Bridge.
