Question

a wire of resistance R is cut in 4 equal parts. these parts are connected in parallel. if the equivalent resistance of this combination is Rp then find the ratio R/Rp

Answer 1

Answer:

the ratio is 16:1.. ....................... .........

Answer 2

Let's say the total resistance of the wire before cutting wasR.

When we cut the wire into 5 parts,

each one has a length of l5 and all other parameters remain unchanged.

So the resistance of each new segment isR5.
