What is the other name of metre bridge?
A meter bridge also called a slide wire bridge is an instrument that works on the principle of a Wheatstone bridge. A meter bridge is used in finding the unknown resistance of a conductor as that of in a Wheatstone bridge.
What does meter bridge measure?
A Meter bridge is used to calculate resistance values with high accuracy. They work on the principle of a balanced Wheatstone bridge. Created by Mahesh Shenoy.
What is the basic principle of meter bridge experiment?
The meter bridge principle is based on the Wheatstone Bridge circuit which says that if at any point or length (of a wire), the ratio of two resistances (say R1 and R2) is equal to the ratio of another two resistances (say R3 and R4 where R4 is the unknown resistance), then there shall be no flow of current at that …
What is the conclusion in meter bridge experiment?
Conclusion: This lab effectively showed how the metre bridge based on Wheatstone bridge provides a mechanism to calculate an unknown resistance using the known relationships given through the resistivity correlation to length.
Why is meter bridge named so?
The reason why this bridge is called the Meter Bridge is because of the fact that it works on the Wheatstone bridge’s principle. So, people also popularly call it Wheatstone’s meter bridge. Another thing is that the wire length used in this circuit is 1 meter, so it has got its name as a meter bridge.
Why is Metre bridge so named?
A meter bridge works on the principle of Wheatstone’s network and is known as Wheatstone’s meterbridge. The length of the wire used is one meter, so it is called meterbridge.
What is the difference between potentiometer and Metre bridge?
The potentiometer is used for determining the emf of the cell whereas the meter bridge is used for determining the unknown resistance. The wire used in the potentiometer is of the 6 to 10 meters in length whereas in the meter bridge the length of the wire is 1 meter.
Why commutator is used in meter bridge?
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit.
What is Wheatstone meter bridge?
A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component.
Why is a meter bridge also called a slide wire bridge?
This is because during experiment, the jockey is to be slided over the bridge wire.
Why is Metre bridge so called?
Why is it called a meter bridge?
The reason why this bridge is called as Meter Bridge is because of the fact that it works on the Wheatstone bridge’s principle. So, people also popularly call it as Wheatstone’s meter bridge. Another thing is that the wire length used in this circuit is of 1 meter, so it has got its name as a meter bridge.
