A 1m long wire is broken into two unequal parts X and Y The X part of the wire is starched into another wire W. Length of W is twice the length of X and the resistance of W is twice that of Y. Find the ratio of length of X and Y.
Text Solution
Verified by ExpertsThe correct answer is:
B
When wire is stretched to double of its length, then resistance becomes 4 times
So.
