Question

a piece of wire of resistance R is cut into two equal parts. If their two parts are not connected in parallel, then state how the resistance and resistivity of the combination will change. justify your answer.​

Answer 1

Explanation:

Let the starting resistance is R, now cut it half into two pieces now two resistance is R/2 and R/2 right

now come to the parallel combination

1/Req=1/r1+1/r2

there for.1/(r/2)+1/(r/2)

It will look like.2/R+2/R=4/R

Now R equivalent=R/4 so answer will be R/4

Answer 2
