Question

A piece of metallic wire of resistance r is into 3 equal parts these parts are connected in parallel if the total resistance of this combination is r' then the value of r:r'

Answer 1

Answer:

piece of metallic wire of resistance r is into 3 equal parts these parts are connected in parallel if the total resistance.

.

Answer 2

Explanation:

When the metallic wire having resistance ( r ) .

And when the wire cut into 3 equal pieces then their resistance cannot change then their total resistance is

r' = 3r / r = 3

means r' = 3

So

The ration is

r : 3 Answer.
