The effective resistance of a parallel connection that consists of four wires of equal length equal area of cross section and same material is 0.25 omega. What will be the effective resistance if they are connected in series?

Options

A. `0.5 Omega`
B. `1 Omega`
C. `4 Omega`
D. `0.25 Omega`

Answer

C

Explanation

Let each resistance is R.
`R_(P) = R/4 = 0.25 Omega`
`R = 1 Omega`
Effective resistance `=4R = 4(1) = 4 Omega`
