How is metre bridge used to measure unknown resistance ?

Meter Bridge consists of a 1 meter long standard resistance wire of uniform cross-section held taut between two ends of metallic strip bent at right angle at the ends. There are two gaps, one on the left side and the other on the right side, in the horizontal part of the metallic strip where two resistors, one of which is known and the other unknown are attached. X= 100-l / l *R The knife edge end of the jokey is moved on the wire until the galvanometer shows null reading. Let D be the position of the jokey on the wire, when null reading is obtained. Let ‘r’ be the resistance per centimetre of the standard wire. As the area of cross section of the standard wire is constant, its resistance is proportional to its length.

How to Calculate Metre Bridge?

Metre Bridge calculator uses Final Resistance=(100-Length)/Length*Resistance to calculate the Final Resistance, Metre Bridge is used to measure unknown resistance when value of one of the resistance is known. Final Resistance and is denoted by Ω symbol.

How to calculate Metre Bridge using this online calculator? To use this online calculator for Metre Bridge, enter Length (l) and Resistance (R) and hit the calculate button. Here is how the Metre Bridge calculation can be explained with given input values -> 323.3333 = (100-3)/3*10.

FAQ

What is Metre Bridge?
Metre Bridge is used to measure unknown resistance when value of one of the resistance is known and is represented as Ω=(100-l)/l*R or Final Resistance=(100-Length)/Length*Resistance. Length is the measurement or extent of something from end to end and Resistance is a measure of the opposition to current flow in an electrical circuit. Its S.I unit is ohm.
How to calculate Metre Bridge?
Metre Bridge is used to measure unknown resistance when value of one of the resistance is known is calculated using Final Resistance=(100-Length)/Length*Resistance. To calculate Metre Bridge, you need Length (l) and Resistance (R). With our tool, you need to enter the respective value for Length and Resistance and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
