Question

a 9r resistance is cut into three equal and connected in parallel find the equivalent resistance of the combination​

Answer 1

9r resistance when cut into three equal parts, we obtain 3, 3r resistances.

When these 3r resistances are connected in parallel circuit we get the equivalent resistance as follows...

(1/R)=(1/3)+(1/3)+(1/3)

where 'R' is the required resistance.

Now, (1/R)=(3/3)

And, R=1.

And you have achieved the answer which was troubling you till then.
