Rearranging Resistance Formula: Y = Mx + C

[chunbryan]

how do you rearrange the formula of resistance = (resistivity x length) / 4(d/2)squared to a y=mx+c equation


resistance (R) = (resistivity x length) / 4(d/2)squared
where resistance is the dependant variable, diameter of wire (d) is the dependant variable


what i got was 2 times square root R = (2 x resisitivity x length) x 1/d

help would be appreciated! :D

Since the d² begins in the denominator, why not first take the reciprocal of both sides? That'll move the d² to the numerator. Then apply the square root.

thanks :) i was really stuck :P
thanks again!
