Question

A uniform wire of resistance 100 ohms is cut into 5 equal parts. If these 5 parts are connected in parallel then the equivalent resistance of the combination will be
A)2 ohms B) 4 ohms C)5 ohms D) 20 ohms​

Answer 1

Answer:

We know that R∝lOn cutting the wire into five equal parts, length of each part becomes one-fifth and hence resistance of each part=R= 550 =10ΩWhen all five wires of resistance R are connected in parallel, equivalent resistance becomes 5R =510=2ΩI hope it's helpful please subscribe me on brainly thank you
