tempinital = 20C

tempfinal = 52.4C

currentInital = .529A

currentFinal = .378A

Voltage = constant but unknownhow do you go about this problem i have tried manipulating ohms law ( I= V/R ) to remove voltage but that always leaves me with IR= IR.

TCOR = temperature coefficient of resistivity;

because the resistance isn't a constant i can't factor it out of RF = RI (1 - TCOR(TF - TI))

i can't use either form because i don't have resistance to solve for resistivity.

if someone could point me in the right direction that would be great.
