Question

In a meter bridge when a wire of resistance 1.5 ohm is used the balance length becomes 50cm .When another wire is used the length becomes 75cm . Find the resistance of the wire

Answer 1

Answer:

Resistance directly proportional to its length

Explanation:

R1/R2=l1/le

1.5/x=50/75

75×1.5=50x

x=2.25
