A) \[\frac{7}{5}\]
B) \[\frac{3}{5}\]
C) \[\frac{5}{3}\]
D) \[\frac{6}{5}\]
Correct Answer: C
Solution :
After adjoining two conductors, the circuit will acquire the form shown in the following figure. From symmetry considerations, we conclude that the central conductor will not be effective in electric charge transfer. Therefore, if the initial resistance \[{{R}_{1}}\] of circuit was \[5\Omega \], where resistance of each conductor is \[1\Omega \], the new- resistance of the circuit will becomeYou need to login to perform this action.
