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

Metre bridge is an instrument that works on the principle of Wheatstone Bridge and is used to find unknown resistance.

• The meter bridge is sensitive when the resistance of all 4 bridge arms is in the same order, and it turns insensitive to extremely high and very low resistances.
• The deflection of the meter bridge will be minimal when resistance is too high. This indicates that the currents are too low.
• As a result, the Metre bridge cannot be used to accurately measure extremely high resistance.
