Question 708: Current Electricity

Question

Resistance n, each of r ohm, when connected in parallel give an equivalent resistance of R ohm.  If these resistances were connected in series, the combination would have a resistance in ohms, equal to

Accepted Answer

$$R = {r \over n} \Rightarrow r = nR$$
When connected in series,  $${R_{eq}} = nr$$
= n (nR) = n
