conductance — noun
1. how easily electricity or heat can move through a material; in physics, it is ca
how easily electricity or heat can move through a material; in physics, it is calculated as one divided by the material's resistance.
Copper has very high conductance, so engineers use it for most home wiring.
subject + has + high/low conductance
Daichi measured the conductance of the salt water with two thin metal probes.
measure + the conductance of + [substance]
Dry wood has very low conductance, which is why it makes a poor electrical wire.
Adding more salt to the water increased its conductance during Esme's chemistry lab.
The new battery design improves thermal conductance between the cells and the cooling plate.
- conductivity
very close; in physics, conductivity refers to a material property, while conductance refers to a specific object's value
- permeability
broader; covers flow of liquids and gases, not just electricity or heat
- resistance
the mathematical opposite — conductance equals 1 divided by resistance
- insulation
the practical opposite; a material with low conductance acts as insulation
用法筆記
Almost always uncountable. Subject is usually a material (copper, water, wood) or a component (battery, wire). Often modified by 'thermal' for the heat-flow sense and 'electrical' for the electricity sense.
