What is the relationship between resistance and conductance?

• A. Conductance = Resistance × Voltage
• B. Conductance = 1/Resistance
• C. Conductance = Voltage × Resistance
• D. Conductance = Resistance × Current

Answer: (B)

The relationship between resistance and conductance is defined by the formula that states conductance is the reciprocal of resistance. This means that as resistance increases, conductance decreases, and vice versa. Conductance quantifies how easily electric current can flow through a material, whereas resistance quantifies how much a material opposes the flow of current.

In this context, if you take a resistor with a certain resistance value, the conductance can be directly calculated by taking 1 divided by that resistance value. For example, if a resistor has a resistance of 10 ohms, then its conductance would be 1/10, or 0.1 siemens.

That relationship is foundational in electrical engineering and circuit analysis, particularly when dealing with Ohm's Law and circuit calculations, ensuring a comprehensive understanding of how electrical components interact.
