A uniform wire of resistance R is cut intotwo Equal halves and these half are joinedin parallel. What is the resistance of thewire.​

Answer»

Answer:

R/4 will be the RESISTANCE.

Explanation:

Given the resistance of the uniform wire is R.

If we cut it into two equal half

Then resistance of the ONE part of wire will be R/2 and that of another part will be R/2

Since these wires are connected in parallel

So, 1/Req = 1/ (R/2) + 1/(R/2)

⇒2/R + 2/R

⇒4/R

Now we have 1/Req = 4/R

So Req = R/4
