The effective resistance of a parallel connection that consists of four wires of equal length, equal area of cross-section and same material is 
. What will be the effective resistance, if they are connected in series? [NEET 2021]
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The four resistances have equal length, equal cross-sectional area and same material.
So, 
(say)
Given, the effective resistance,
For parallel arrangement,
For series combination,
