Current Electricity Charging Discharging Of Capacitors Question 349

Question: In the above question, the resistance between the square faces is

[MP PET 1993]

Options:

A) $ 3\times {{10}^{-9}}ohm $

B) $ 3\times {{10}^{-7}}ohm $

C) $ 3\times {{10}^{-5}}ohm $

D) $ 3\times {{10}^{-3}}ohm $

Show Answer

Answer:

Correct Answer: D

Solution:

In the above question for calculating equivalent resistance between two opposite square faces. $ l=100cm=1m,A=1cm^{2}=10^{4}m^{2} $ , so resistance $ R=3\times 10^{7}\times \frac{1}{{{10}^{-4}}}=3\times 10^{3}\Omega $
