Question

A wire of resistance R is cut into n equal parts. These parts are then connected in parallel. The equivant
resistance of the combination will be
A.nR
B.R/n
C.n/R
D.R/n^2​

Answer 1

Answer:

as t

Explanation:

as the resistor is cut into n equal parts so resistance of each part become r/n

Now they are connected in parallel so equivalent resistance =

$\frac{1}{n}times \: of \: resistance \: of \: one \: resistor$

so

$equivalent \: resistance = \frac{1}{n} \frac{r}{n}$

so equivalent resistance =

$\frac{r}{ {n}^{2} }$
