A wire is bent in the form of a triangle now the equivalent resistance R between its one end and the mid point of the side is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Resistances R, R and 
are in series, their resultant resistance,
R' = R + R + 
= 
Resistances R’ and 
are in parallel. Their resultant resistance
= 
+ 
= 
R = 
R' = R + R + 
= 
= 
+ 
= 
R =
