Question
When is the metre bridge most sensitive?
Open in App
Solution
The metre bridge is more sensitive when all resistances are of the same order.
If we measure very high or very low resistances, the balancing length will be very small, then the resistances of the connecting metallic strips cannot be neglected and the relation of balance point will not yield correct results.
