Conductance to Resistance Formula:
| From: | To: |
Conductance (G) and resistance (R) are reciprocal electrical properties that describe how easily current flows through a material. Conductance measures how well a material conducts electricity, while resistance measures how much it opposes current flow.
The calculator uses the fundamental electrical relationship:
Where:
Explanation: This inverse relationship means that as conductance increases, resistance decreases, and vice versa. High conductance indicates good conductivity, while high resistance indicates poor conductivity.
Details: Understanding the relationship between conductance and resistance is fundamental in electrical engineering, circuit design, and material science. It helps in selecting appropriate materials for specific applications and analyzing circuit performance.
Tips: Enter the conductance value in siemens (S). The value must be greater than zero. The calculator will compute the equivalent resistance in ohms (Ω).
Q1: What is the unit of conductance?
A: The SI unit of conductance is the siemens (S), which is equivalent to 1 ampere per volt (A/V).
Q2: How are conductance and conductivity related?
A: Conductance is the property of a specific object, while conductivity is an intrinsic property of a material. Conductance depends on both the material and its dimensions.
Q3: What is a typical range for conductance values?
A: Conductance values can range from very small (nanosiemens for insulators) to very large (kilosiemens for good conductors like copper).
Q4: Can resistance be calculated from conductance for AC circuits?
A: For AC circuits, impedance (Z) replaces resistance, and admittance (Y) replaces conductance, following the same reciprocal relationship: Y = 1/Z.
Q5: Why is this conversion important in practical applications?
A: This conversion is essential for circuit analysis, component selection, troubleshooting electrical systems, and understanding material properties in various engineering applications.
