Conductance and Resistance Formula:
| From: | To: |
The conductance and resistance formula describes the inverse relationship between electrical conductance (G) and electrical resistance (R). Conductance measures how easily electric current flows through a material, while resistance measures how much the material opposes the flow of electric current.
The calculator uses the fundamental electrical formula:
Where:
Explanation: This formula shows that conductance is the reciprocal of resistance. As resistance increases, conductance decreases, and vice versa.
Details: Understanding the relationship between conductance and resistance is fundamental in electrical engineering, circuit design, and material science. It helps in analyzing circuit performance, selecting appropriate materials, and designing efficient electrical systems.
Tips: Enter the resistance value in Ohms (Ω). The value must be greater than zero. The calculator will automatically compute the corresponding conductance in Siemens (S).
Q1: What is the unit of conductance?
A: The SI unit of conductance is Siemens (S), formerly known as mho.
Q2: How does temperature affect conductance and resistance?
A: For most conductors, resistance increases with temperature, which means conductance decreases. For semiconductors, the relationship can be more complex.
Q3: What is 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 independent of its size or shape.
Q4: Can conductance be negative?
A: No, conductance is always a positive value since resistance is always positive for passive components.
Q5: What are typical conductance values for common materials?
A: Conductors like copper have high conductance (low resistance), insulators like rubber have very low conductance (high resistance), and semiconductors have intermediate values.
