Question

Can you find very high resistance accurately with the help of a Metre bridge$?$

Answer 1

1. Metre bridge: Metre bridge is an instrument that works on the principle of Wheatstone’s bridge and it is used to find the unknown resistance.
2. The meter bridge is sensitive when the resistance of all four bridge arms is of the same order, and it becomes insensitive to very high and very low resistances.
3. The deflection of the meter bridge will be extremely minimal if the resistance is too high. This also indicates that the currents are too low.
4. As a result, we can't use a Metre bridge to accurately measure very high resistance.
