Why meter bridge is used in this experiment?
Meter bridge experiment is used to verify the laws of resistance and to calculate unknown resistances. The general name of the bridge is slide-wire bridge but is called meter bridge since the wire used in the bridge is often a meter long.
Which material is used for meter bridge?
Alloy NiChrome is very resistant to corrosion and it has a very high melting point around 1400∘Cwhich makes it highly popular in making meter bridge wire.
What is meter bridge explain?
Hint: A meter bridge is an electrical apparatus that helps in determining the value of unknown resistance of a metal coil. Complete step by step answer: Meter Bridge works on the principle of the Wheatstone bridge. A Wheatstone bridge is an electrical network which is used to calculate the value of unknown resistance.
What is the working principle of meter bridge?
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 known as meter 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.
Can copper wire used in meter bridge?
Complete answer: Meter bridge is a device that is used to calculate the resistance(which is unknown) of a conductor. In meter-bridge, the principle that is used is called a wheatstone bridge. Thus, copper, due to its low resistance and high temperature coefficient of resistance, cannot be used in meter bridges.
What is a meter bridge and how is it used?
A meter bridge is an electrical instrument which is used to determine the resistance of a given conductor. It can be also used to calculate the effective series and parallel equivalent of resistances.
How to find the resistance of a meter bridge?
The devices required in finding the unknown resistance of a conductor using a meter bridge are: 1 Meter bridge 2 Resistance box 3 Galvanometer 4 Unknown Resistance of a length 1 m 5 Screw gauge 6 Connecting Wires 7 Jockey 8 One way key More
What does are stand for in meter bridge?
R is an unknown resistance connected across one of the gaps. Across the other gap, we connect a standard known resistance S. The jockey is connected to some point D on the wire, a distance l1 is the resistance of the wire per unit centimeter. The portion DC of the wire similarly has a resistance Rcm ).
What do you call a slide wire bridge?
Meter 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 Is Wheatstone Bridge?
