Question

a 9 ohm resistance is cut into three equal parts and connected in parallel.find the equivalent resistance of the combination.


​

Answer 1

Answer:

1 ohm

Explanation:

As 9 Ohm cut down in 3 equal parts.

It means Resistance of each wire = 3 Ohm

We know,

Parallel Equivalent Resistance

1/r = 1/3 + 1/3 + 1/3

1/r = 3/3

1/r = 1 Ohm
