Alcohen2006 Answered:

Energy dissipated (heat) = (current through it, squared) times (resistance).

Equivalent, for other situations:

Energy dissipated (heat) = (voltage across it, squared) divided by (resistance)

All in all, I'd rather be in Cleveland.

by joules heat eqn

H=(I^2)Rt

where H=heat generated

I=current

R=resistance

t=time for which current flows

The equation for the heat that is generated is: R*i^2  (R = resistance [Ohms], i = current [Amperes]).
