Disadvantages of Wheatstone’s Bridge
Various disadvantages of the Wheatstone’s Bridge are,
- The result of Wheatstone’s Bridge can be easily affected by temperature and EMF cells.
- Wheatstone bridge may also get affected if the galvanometer is not of good quality.
- Wheatstone Bridge fails if it is not in a balanced condition.
- We can’t measure large resistance with the help of Wheatstone’s Bridge.
- The cost of maintaining the Wheatstone Bridge is very high.
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!
