Question

A resistance of 24 Ω is connected in the left gap of the meter bridge.

Two resistors of 10 Ω and 15 Ω are connected in parallel in the right

gap. Find the position of null point of the meter bridge from the left

end​

Answer 1

Answer:

Answer:

The resistance (R) in the left gap is 1.5 Ω

Given:

Resistance in the right gap (S) = 3.5 Ω

Explanation:

We know that the length from left side is l₁ = 30 cm. and, from previous knowledge we know that length of meter bridge is 1 m or 100 cm.

So, let the length on the right side be 100 - l₁ cm.

And, we know that if there is no flow of current in the galvanometer it is a balanced Wheatstone bridge.

Substituting the values,

∴ The resistance (R) in the left gap is 1.5 Ω.
