A) nR
B) \[\frac{R}{n}\]
C) \[\frac{n}{R}\]
D) \[\frac{R}{{{n}^{2}}}\]
Correct Answer: D
Solution :
[d] Resistance of each of the equal parts of the wire \[=\frac{R}{n}\](=r say) The effective resistance of n wires in parallel \[=\frac{r}{n}\] \[=\left( \frac{R}{n} \right)\times \frac{1}{n}\] \[=\frac{R}{{{n}^{2}}}\]You need to login to perform this action.
