Best ResponseYou've already chosen the best response.1\[V = IR\] \[P = IV\] \[R = \frac{ \delta L }{ A }\] i used the first one (R=V/I) is that right?

Best ResponseYou've already chosen the best response.1once you find R , use that and given diameter and length to find resistivity which is \[\delta\]
