A) R
B) R/2
C) R/4
D) None of these
Correct Answer: A
Solution :
The resistance of two arms on the opposite corners of a square = R + R = 2R. Therefore, for equivalent resistance between two opposite corners of a square, we have two resistance each of value 2R in parallel. So, \[\frac{1}{R}=\frac{1}{2R}+\frac{1}{2R}\] \[\frac{1}{R}=\frac{1+1}{2R}+\frac{2}{2R}\] R = RYou need to login to perform this action.
