Conductivity is the amount of heat that moves through a slab with a unit cross-sectional area per second.
Electrical conductivity is the amount of electricity that flows through a comparable slab per second when the potential gradient is unity.
Examples of conductivity
Example of heat conductivity: The act of heating a pan on a stove is a typical illustration of conduction. The surface of the pan receives heat directly from the burner. The amount of kinetic energy that the particles in a sample of matter have converted to heat is measured by temperature.
Example of electricity conductivity: Your home's wiring carries electricity, enabling lights to turn on when a switch is flipped. Electrical conduction is what powers your computer and all other electric or battery-operated devices and appliances when you turn them on.
