Electric Conductance: Definition, Units, Applications and Unit Conversions
Electric conductance is the measure of how easily electric current flows through a conductor or electrical component. It is the reciprocal of electrical resistance and is an essential quantity in electrical engineering, electronics, telecommunications, power systems, and scientific research. Conductance helps engineers evaluate the efficiency of electrical circuits and conductive materials.
What is Electric Conductance?
Electric conductance expresses a material's or component's ability to conduct electric current. A conductor with high conductance allows current to flow easily, while one with low conductance restricts current flow. Conductance depends on the material's electrical properties, dimensions, and temperature.
SI Unit of Electric Conductance
The SI derived unit of electric conductance is the siemens (S). One siemens represents the conductance of a conductor whose resistance is exactly one ohm.
Common Conductance Units
- Siemens (S)
- Millisiemens (mS)
- Microsiemens (µS)
- Kilosiemens (kS)
- Megasiemens (MS)
- Mho (℧)
- Statmho
- Abmho
Applications
Electric conductance is widely used in electrical engineering, electronics, electrochemistry, water quality analysis, telecommunications, industrial automation, semiconductor manufacturing, and scientific laboratories. It is also used to evaluate conductive materials, sensors, electrolytes, and electronic components.
Relationship with Other Physical Quantities
- Conductance = 1 ÷ Resistance
- Conductance = Current ÷ Voltage
- Resistance = 1 ÷ Conductance
- Electrical Power = Voltage² × Conductance
