Conductance Formula:
From: | To: |
Electrical conductance (G) is the measure of a material's ability to allow the flow of electric current. It is the reciprocal of electrical resistance (R) and is measured in siemens (S).
The calculator uses the conductance formula:
Where:
Explanation: The formula shows the inverse relationship between conductance and resistance. As resistance increases, conductance decreases, and vice versa.
Details: Conductance calculations are essential in electrical engineering, circuit design, and material science. They help determine how easily current can flow through a component or material, which is crucial for designing efficient electrical systems.
Tips: Enter resistance value in ohms (Ω). The value must be greater than zero. The calculator will compute the corresponding conductance in siemens (S).
Q1: What is the relationship between conductance and resistance?
A: Conductance and resistance have an inverse relationship. Conductance (G) is the reciprocal of resistance (R), expressed as G = 1/R.
Q2: What are the units of conductance?
A: The SI unit of conductance is the siemens (S), which is equivalent to 1/ohm or ampere/volt.
Q3: What is a typical conductance value for copper wire?
A: Copper has high conductance, typically around 58.0 × 10⁶ S/m at 20°C, making it an excellent conductor.
Q4: How does temperature affect conductance?
A: For most conductors, conductance decreases as temperature increases due to increased atomic vibrations that impede electron flow.
Q5: What's the difference between conductance and conductivity?
A: Conductance is the property of a specific object or component, while conductivity is an intrinsic property of a material (conductance per unit length and cross-sectional area).
