How does the resistance of a wire is affected if it’s diameter is tripled
Asked by Keshavaggarwal28 | 12 Feb, 2019, 07:04: AM
answered-by-expert Expert Answer
Resistance of the wire is inversely proportional to cross section area of wire. So if you triple the wire diameter then the resistance of wire will become 1/9 of its initial value.
