A) r
B) 3r
C) \[\frac{r}{3}\]
D) \[\frac{2}{3}r\]
Correct Answer: C
Solution :
The given network resistances can be replaced successively by the networks. Hence, the three resistors are connected in parallel, hence equivalent resistance is \[\frac{1}{R}=\frac{1}{r}+\frac{1}{r}+\frac{1}{r}=\frac{3}{r}\Rightarrow R=\frac{r}{3}\]You need to login to perform this action.
