A) \[\frac{4}{3}\pi \times {{10}^{-6}}\Omega \]
B) \[\frac{2}{3}\pi \times {{10}^{-6}}\Omega \]
C) \[0.88\times {{10}^{-6}}\Omega \]
D) \[14\pi \times {{10}^{-6}}\Omega \]
Correct Answer: C
Solution :
Resistance across \[AB=\frac{1}{R'}=\frac{1}{R}+\frac{1}{R}+\frac{1}{{{R}_{1}}}\] \[{{R}_{1}}=2\times {{10}^{-6}}\Omega \] and \[R=\pi \times 1\times {{10}^{-6}}\Omega \] On solving, \[R'=0.88\times {{10}^{-6}}\Omega \]You need to login to perform this action.
