Heat Current, Temperature Gradient, Thermal Resistance & Conductivity Thermodynamics & Physics

This physics video tutorial provides a basic introduction into heat current. It explains how to calculate the heat current flowing in a metal from a hot region to a cold region. The heat current is simply the rate at which heat energy is transferred. In addition, it explains how to calculate the temperature gradient and how to use it to find the steady state temperature any where between the hot and cold regions. Finally, this video explains how to calculate the thermal resistance given the length of the metal bar and the thermal conductivity. In addition, this video explains how to calculate the junction temperature between two dissimilar metals. This heat transfer video tutorial contains plenty of examples and practice problems.
