Explain the construction of meter bridge.

A meter bridge has a straight and uniform wire of materials such as Manganin.

  • The wire is of one-meter length and is stretched along the side of a meter scale AC.
  • The ends of the wire are attached to thick copper strips of L shape with negligible resistance at A and C.
  • The L-shaped copper stripes and the wire are mounted on a wooden base horizontally.
  • Between the two L-shaped copper strips, another thick copper strip D having negligible resistance is fixed in a way that two gaps are formed. 

Meter Bridge

In the AD gap, a resistance R is connected whose value is to be measured. In the CD gap, a resistance box S is connected. To complete the Wheatstone bridge, resistances P and Q are formed by dividing the meter bridge wire into parts using a jockey which changes P and Q continuously.
