Question

Piece of a wire having a resistance of 5 ohm cut into 5 equal parts, if the five parts of the wore are connected in parallel then find the effective resistance of the combination

Answer 1

Answer:

Here is your Answer

Explanation:

when a uniform wire of resistance 50 ohm, is cut into 5 equal parts, resistance of each part will be 50/5=10 ohm.

Now if these 5 wires of resistance 10 ohm each are connected in parallel, equivalent resistance R is given by

1/R=1/10+1/10+1/10+1/10+1/10

or 1/R=1/2

or R=2 ohm
