Suppose a wire of resistance R is stretched uniformly unless its length becomes twice (2L) its original length (L). What is the new resistance? A wire has a resistance of R. What will the wire's resistance be if it is stretched to four times its original length without...
Resistance of Wire: First we have to understand the resistance of a wire for solving this problem: The resistance of wire is depends upon the material out of which the wire is made and also depends upon the length and cross-section area of the wire. S...
