Question

A wire connected in the left gap of meter bridge balance a 10 resistance in the right gap to a point which divides the bridge wire in the ratio 3:2 if the length of the wire is 1m the length of 1ohm wire is

Answer 1

Answer:

Correct option is

A

1.0×10

−1

m

Given,

R:S=3:2

S=10Ω

Ratio,

S

R

=

2

3

R=

2

3

×10=15Ω

The length of 1Ω wire is given by

l=

15

1.5

l=

10

1

⇒0.1 m or 1.0×10

−1

m

Explanation:

hope this help and if you cant find the answer ....1.0×10 -¹m

this is the answer
