= Heat current
{wiki=Heat_current}
Heat current, also known as thermal current, refers to the rate at which heat energy is transferred from one location to another, typically measured in watts (W). It describes the flow of thermal energy due to a temperature difference between two bodies or regions. Heat current can occur through various mechanisms, including conduction, convection, and radiation: 1. **Conduction**: Heat is transferred through direct contact between materials, where differing temperatures cause heat to flow from the hotter object to the cooler one.
