Drawbacks of meter bridge experiment

A meter bridge is a device that is used to measure the resistance of a metal coil. Some drawbacks of meter bridge are as given below:

  • Since the bridge is most sensitive at 50 cm length, it wouldn’t be appropriate for measuring increasing or decreasing resistance.
  • The meter bridge wire might not be approximately one meter long, which results in measurement inaccuracy.
