The equivalent resistance of combination is .
Explanation:
Length of wire is 10 m and resistance 10 ohms is cut into 10 equal parts. These parts are now connected in parallel, then the resistance of each part becomes r ohms, r=R/10
We need to find the equivalent resistance of combination.
For parallel combination, the equivalent resistance is given by :
We have R = 10 ohms
So,
So, the equivalent resistance of combination is .
