In an experiment of meter bridge, a null point is obtaining at the center of the bridge wire. When a resistance of `10 ohm` is connected in one gap, the value of resistance other gap is

A

`10 Omega`

B

`5 Omega`

C

`(1)/(5) Omega`

D

`500 Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Wheatstone bridge is balanced, therefore
`(P)/(Q) = (R )/(S)` or `1 = (10)/(S) implies s = 10 ohm`

In a meter bridge the null point is obtained at the middle point of the wire. If in one gap the resistance is 10 Omega , then the value of resistance in the other gap is :–

Two coils are connected in series in one gap of the Wheatstone's meter bridge and null point is obtained at the centre of the wire with a resistance of 100 Omega in the other gap. When the two coils are connected in parallel in the same gap, the unknown resistance is to be changed by 84 Omega to obtain the null point at the centre again. The resistance of the two coils will be

Two resistances are connected in the two gaps of a meter bridge. The balance point is 20 cm from the zero end. When a resistance 15 Omega is connected in series with the smaller of two resistance, the null point+ shifts to 40 cm . The smaller of the two resistance has the value.

Two unknown resistances are connected in two gaps of a meter-bridge. The null point is obtained at 40 cm from left end. A 30Omega resistance is connected in series with the smaller of the two resistances, the null point shifts by 20 cm to the right end. The value of smaller resistance in Omega is
