Conductance Formula:
| From: | To: |
Conductance (G) is the measure of a material's ability to conduct electric current. It is the reciprocal of resistance and is measured in siemens (S). Higher conductance indicates better conductivity of the material.
The calculator uses the fundamental conductance formula:
Where:
Explanation: Conductance represents how easily electric current flows through a material when a voltage is applied. It is directly proportional to current and inversely proportional to voltage.
Details: Conductance calculations are essential in electrical engineering, circuit design, material science, and quality control of conductive materials. It helps determine the efficiency of electrical components and systems.
Tips: Enter current in amperes (A) and voltage in volts (V). Both values must be positive and non-zero. The calculator will compute the conductance in siemens (S).
Q1: What is the relationship between conductance and resistance?
A: Conductance is the reciprocal of resistance: G = 1/R. Higher conductance means lower resistance and better conductivity.
Q2: What are typical conductance values for common materials?
A: Conductors like copper have high conductance (≈ 58 MS/m), while insulators like glass have very low conductance (≈ 10⁻¹² S/m).
Q3: How does temperature affect conductance?
A: For metals, conductance decreases with increasing temperature, while for semiconductors, conductance increases with temperature.
Q4: What is the difference between conductance and conductivity?
A: Conductance is a property of a specific object, while conductivity is an intrinsic property of the material itself, independent of size and shape.
Q5: When is conductance measurement important?
A: Important in circuit analysis, material selection for electrical applications, quality testing of wires and cables, and designing efficient electrical systems.
