If a wire is stretched to double its length, what will its new resistance be?Question:If a wire is stretched to double its length, what will its new resistance be?Resistance:It is defined as the property of a material to show hindrance against the current flowing in the...
To calculate the resistance of a wire: Find out the resistivity of the material the wire is made of at the desired temperature. Determine the wire's length and cross-sectional area. Divide the length of the wire by its cross-sectional area. Multiply the result from Step 3 by the resistivi...
Using this website, users can quickly measure the resistance of a wire using the known wire length and gauge values. An advanced wire calculator is also provided by it that takes various values into account before calculating the wire resistance like contact resistance, wire resistance variations,...
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. Suppose {eq}L {/e...
