Resistance Formula:
| From: | To: |
Resistance is a measure of the opposition to current flow in an electrical circuit. Its S.I unit is ohm. Conductance (also known as electrical conductance) is defined as the potential for a substance to conduct electricity.
The calculator uses the resistance formula:
Where:
Explanation: The formula shows the inverse relationship between resistance and conductance in an electrical circuit.
Details: Calculating resistance from conductance is fundamental in electrical engineering and circuit analysis. It helps in designing circuits, analyzing electrical systems, and understanding material properties.
Tips: Enter conductance value in Siemens. The value must be valid (conductance > 0).
Q1: What is the relationship between resistance and conductance?
A: Resistance and conductance are inversely proportional. Higher conductance means lower resistance, and vice versa.
Q2: What are typical units for conductance?
A: The SI unit for conductance is Siemens (S), which is equivalent to 1/Ohm.
Q3: When is this calculation most useful?
A: This calculation is essential when working with conductive materials, circuit analysis, and electrical component design.
Q4: Are there limitations to this formula?
A: This formula assumes linear relationships and may not account for temperature effects or non-ohmic behavior in some materials.
Q5: Can this be used for AC circuits?
A: For AC circuits with reactive components, impedance calculations are more appropriate, though the basic R=1/G relationship still holds for resistive components.
