Resistance vs Conductance
Resistance measures how strongly a material opposes the passage of electric current, dissipating electrical energy as heat ($R = ho L / A$). In contrast, conductance measures the ease with which current flows, calculated as the exact inverse: $G = 1 / R$. A component with 10 $Omega$ resistance has a conductance of 0.1 Siemens.
Frequently Asked Questions
What does 1 Siemens equal?
1 Siemens (S) is the conductance of a conductor with an electrical resistance of exactly 1 Ohm ($1 ext{ S} = 1/Omega = 1 ext{ A/V}$).
