Question

If 'n' number of resistors each equal to R are
connected in series then their equaivalent resistance is
(a) nR (b) n²R (c) R/n (d) R/n square​

Answer 1

Answer:

The correct option is (a) nR.

Explanation:

Let the number of resistors connected in series be 3.

Then the effective resistance=R1+R2+R3.

= number of resistors * resistance value.

Here, the number of resistors connected in series is n.

Then the effective resistance = R1+R2+R3+........Rn.

That is also equal to :

number of resistors * resistance value

let the resistance value be R

=n*R

=nR

Therefore the option (a) nR is correct.
