Question

Define 1 ohm resistance.
A student has a resistance wire of 1 ohm. If the length of this wire is 50 cm, to what
length he should stretch it uniformly so as to obtain a wire of 4 Omega resistance? Justify
your answer .

Answer 1

Answer:

If 1A current flows through a conductor and the potential difference across its two end is 1V then the resistance is said to be 1 ohm.

Answer 2

Answer:

200cm

Explanation:

by stretching the wire up to 200cm then we get 4ohm
