Ok so as fare as I understand the equation for Joule heating in a material with a DC current is I^2*R. I am trying to calculate for the heating of carbon fiber in an argon environment. Carbon fiber has a resistivity similar to graphite (roughly 5.0*10^-7) I am trying to calculate for 3.3VDc. However I am getting a massive value of 14291338.58 watts dissipated. To get the value of I I'm using the equation V/R=I. What am I doing wrong? I feel 14.2 megawatts is a bit off.
