A) Equal
B) One fourth
C) One eight
D) \[\frac{1}{16}th\]
Correct Answer: D
Solution :
Let the resistance of the wire be R, then we know that resistance is proportional to the length of the wire. So each of the four wires will have R/4 resistance and they are connected in parallel. So the effective resistance will be \[\frac{1}{{{R}_{1}}}=\left( \frac{4}{R} \right)4\Rightarrow {{R}_{1}}=\frac{R}{16}\]You need to login to perform this action.
