Joule′s Laws
Describe the heat produced when a current flows through a resistance and the internal energy of an ideal gas.
Joule's First Law
The heat produced when a current flows through a resistance for a specified time:
Where
Q = heat produced [J]
I = current [A]
R = resistance [Ω]
t = time [s]
Joule's Second Law
The internal energy of an ideal gas is independent of its volume and pressure, depending only on its temperature.
