What should be the length of a nichrome wire of resistance `4.5 Omega`, if the length of a similar wire is `60 cm` and resistance `2.5 Omega` ?

A wire of length 3 m connected in the left gap of a metre bridge balances a 8 Omega resistance in the right gap at a point, which divides the bridge wire in the ratio of 3 :2 . What is the length of the wire corresponding to a resistance of the length of the wire corresponding to a resistance of 1 Omega ?

The resistance of a 1m long nichrome wire is 6 Omega . If we reduce the length of the wire to 70 cm, what will its resistance be?

The resistance of wire is 10 Omega IF the length of wire is increase by n% the new resistance is 10.2 Omega then n…..

A wire of resistance 4 Omega is stretched to four times of its original length resistance of wire now becomes

The resistance of a copper wire of length 5 m is 0.5 Omega. If the diameter of the wire is 0.05 cm, determine its specific resistance.

A wire of resistance 2.20 Omega has a length 2m . Calculate the length of the similar wire which connected in parallel with 2m length wire will give a resistance of 2.0 Omega

A wire of resistance 4 Omega is stretched to twice its original length.The resistance of stretched wire would be

A wire of resistance 4 Omega is stretched to twice its original length. The resistance of stretched wire would be
