What is a meter bridge class 12?

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 meter bridge is a way of construction of a Wheatstone network.

What is meter bridge and why is it called so?

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.

What is the main aim of meter bridge experiment?

METRE BRIDGE – 1 AIM:- To find the resistance of the given wire using meter bridge and hence determine the specific resistance of its material. APPARATUS: A meter bridge, galvanometer, one way key, a resistance box, a battery jockey, unknown resistance wire about 1 meter long, screw gauge and connecting wires.

What is meter bridge How is the resistance measured by it?

The meter bridge uses the same principle as the Wheatstone Bridge. It is used to find the unknown Resistance of the Material. The meter bridge consists of a wire of 100 cm, a scale, one unknown Resistor, one known Resistor or a Resistance Box, a Galvanometer and a jockey.

What is difference between Wheatstone bridge and meter bridge?

The difference between potentiometer and meter bridge is given below: The potentiometer is based on the potential balance while the meter bridge is based on the Wheatstone bridge. 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 do we use meter bridge?

A Meter bridge is used to calculate resistance values with high accuracy. They work on the principle of a balanced Wheatstone bridge.

What is the aim of Metre bridge experiment?

Which cell is used in meter bridge?

leclanche cell used for the experiment of meter bridge because it is so easy to mke it & EMF is grater than Daniel cell.

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. One of the Wheatstone bridge’s initial uses was for soils analysis and comparison.

Why copper strips are used in meter bridge?

Why thick copper strips are used in meter bridge? The connection between the resistors in the metre bridge is done using thick copper wires. Copper has very low resistivity. By using thick copper wires the resistivity is reduced further.

What is meter bridge formula?

The metre bridge, also known as the slide wire bridge consists of a one metre long wire of uniform cross sectional area, fixed on a wooden block. A scale is attached to the block. ρ=Lπr2X ; Where L be the length of the wire and r be its radius.

What is the definition of meter bridge?

A meter bridge is defined as a uniform resistance wire 1 meter in length, mounted above a scale marked in millimeters, with terminals added to make the device usable as either part of a Wheatstone bridge or of a potentiometer.

How important is that meter bridge?

They have a huge significance in science. A Meter Bridge is a kind of an electric device that assists in the measurement of an unidentified resistance. On the other hand, a potentiometer is also an electric device that is used for the measurement of the internal resistance and the EMF or electro motive force of cells.

Wheatstone Bridge Application The Wheatstone bridge is used for the precise measurement of low resistance. Wheatstone bridge along with operational amplifier is used to measure physical parameters such as temperature, light, and strain. Quantities such as impedance, inductance, and capacitance can be measured using variations on the Wheatstone bridge.
