1. the ability of a material to conduct electricity, heat, or sound
Usage: physics; engineering
2. a measure of how easily electric current flows through a material, equal to the reciprocal of resistance
Usage: electrical engineering; measured in siemens

Examples

• The conductance of copper makes it ideal for electrical wiring.
• Scientists measured the thermal conductance of the new material.
• High conductance allows electricity to flow with minimal energy loss.
• The conductance of the circuit decreased when we added more resistors.
• Water’s conductance increases when salt is dissolved in it.
• The engineer calculated the conductance to determine the wire gauge needed.
