Resistance Formula:
From: | To: |
Conductance to resistance conversion is a fundamental electrical calculation that determines the resistance of a material based on its conductance. For metals, this relationship is defined by the simple inverse relationship R = 1/G, where R is resistance in ohms (Ω) and G is conductance in siemens (S).
The calculator uses the resistance formula:
Where:
Explanation: Conductance is the reciprocal of resistance, meaning materials with high conductance have low resistance, and vice versa.
Details: Calculating resistance from conductance is essential in electrical engineering, circuit design, and material science. It helps determine how easily electric current can flow through a metal conductor.
Tips: Enter the conductance value in siemens (S). The value must be greater than zero. The calculator will compute the corresponding resistance in ohms (Ω).
Q1: What is the relationship between conductance and resistance?
A: Conductance and resistance are reciprocals of each other. If you know one value, you can calculate the other using R = 1/G or G = 1/R.
Q2: Why is this calculation important for metals?
A: Metals are common conductors in electrical systems. Understanding their resistance helps in selecting appropriate materials for wires, circuits, and electrical components.
Q3: What units are used for conductance and resistance?
A: Conductance is measured in siemens (S), and resistance is measured in ohms (Ω).
Q4: Can conductance be zero?
A: No, conductance cannot be zero as it would make resistance infinite. In practical terms, all conductors have some finite conductance value.
Q5: How does temperature affect conductance and resistance?
A: For most metals, resistance increases with temperature, which means conductance decreases as temperature rises.
