What are the drawbacks of the meter bridge experiment?

Answer 1

Drawbacks of meter bridge experiment

Meter bridge: A device used to measure the resistance of a metal coil, is called a meter bridge.

Some drawbacks are provided below:

1. Since the bridge is perhaps most sensitive at a length $50\mathrm{cm}$, it would not be appropriate for measuring increasing or decreasing resistance.
2. The meter bridge wire might not have been approximately one meter long, resulting in measurement inaccuracy.
