Frequently Asked Questions
Everything you need to know about electrical conductance, units, formulas, and physical principles.
Q:What is electrical conductance and how is it related to resistance?
Electrical conductance (G) measures how easily electric current flows through a material or component. It is the mathematical reciprocal of electrical resistance (R): G = 1 / R. While resistance is measured in Ohms (Ω), conductance is measured in Siemens (S). A component with low resistance exhibits high conductance, and vice versa.
Q:What is the difference between Siemens (S) and Mhos (℧)?
Siemens (S) and Mhos (℧) represent the exact same physical quantity: 1 S = 1 ℧. The term 'mho' was coined by Sir William Thomson (Lord Kelvin) by spelling 'ohm' backwards, accompanied by an inverted omega symbol. In 1971, the 14th General Conference on Weights and Measures adopted the Siemens (named after Werner von Siemens) as the official SI unit.
Q:What are Abmho and Statmho, and where are they used?
Abmho and Statmho belong to the CGS (Centimeter-Gram-Second) unit system. 1 Abmho equals 10⁹ Siemens (electromagnetic CGS unit), while 1 Statmho equals approximately 1.11265 × 10⁻¹² Siemens (electrostatic CGS unit). They appear primarily in legacy physics literature, theoretical electrodynamics, and astrophysical plasma equations.
Q:How does temperature affect electrical conductance in metals?
In metallic conductors, electrical resistance increases with temperature due to increased thermal vibrations of atomic lattice ions, which scatter free electrons. Consequently, conductance decreases: G(T) = G₀ / (1 + α(T - T₀)), where α is the material's temperature coefficient (approx. 0.00393/°C for copper at 20°C).
Q:What is the distinction between conductance (G) and conductivity (σ)?
Conductance (G) is an extensive property of a specific object or wire, dependent on its physical dimensions (cross-section and length) and measured in Siemens (S). Conductivity (σ) is an intrinsic intensive property of the material itself, independent of shape, measured in Siemens per meter (S/m). They relate via G = σ · A / L.
Q:How does the wire simulator calculate the required wire length?
Using the formula G = (σ · A) / L rearranged as L = (σ · A) / G, where A is the cross-sectional area (1 mm² = 10⁻⁶ m²) and σ is the material's conductivity at 20°C (Copper: 5.96×10⁷ S/m, Aluminum: 3.50×10⁷ S/m, Gold: 4.10×10⁷ S/m, Iron: 1.00×10⁷ S/m).
Q:Why is conductance preferred over resistance in liquid and electrolytic measurements?
In chemistry, hydrology, and water quality analysis, ion concentration in aqueous solutions is directly proportional to electrical conductance (often expressed in µS/cm or mS/cm). Measuring conductance makes it easy to add ionic contributions linearly, whereas working with resistance would require reciprocal calculations.
- G (Conductance): Measured in Siemens (S).
- R (Resistance): Measured in Ohms (Ω).
- I (Current): Measured in Amperes (A).
- V (Voltage): Measured in Volts (V).
