conductors allow heat to be transmitted through them. Examples of conductors are metals, the human body, Earth and animals. The human body is a strong conductor. It, therefore, offers a resistance-free route from a current-carrying wire through the body for the current to flow...
where A is the cross-sectional area of the material, L is the length and κ is the thermal conductivity. The SI units of conductance are W/K (watts per Kelvin). This allows for an interpretation of κ as the thermal conductance of a unit area per unit thickness. Converse...
