Question

A metallic wire of resistance R is cut into ten parts of equal length. Two pieces each are joined in series and then five such combinations are joined in parallel. What will be the effective resistance of the combination?

Answer 1

★★Hey There★★

Here's What you are looking for,

Let , Resistance of a Wire be R
Here, They Said that The Metallic wire is cut into 10 parts of equal length,Then From Row l/A
all are constant

They Have same Resistance
Effective Resistance when Connected in Series,

Rs=R1+R2+R3+...+R10
Rs=R+R+R+R+...10 times
Rs= 10R
