Resistance is inversely proportional to what electrical property?

Resistance is inversely proportional to what electrical property?

• A. Current
• B. Voltage
• C. Conductivity
• D. Capacitance

Answer: (C)

Resistance is inversely proportional to conductivity, which is a measure of a material's ability to conduct electric current. The relationship is defined by the formula: \[ \text{Resistance} = \frac{1}{\text{Conductivity}} \] When conductivity increases, resistance decreases, meaning that materials with higher conductivity are better at allowing the flow of electric current. For instance, metals like copper have high conductivity and, correspondingly, low resistance, making them ideal for electrical applications. Conversely, materials with low conductivity, such as rubber, have high resistance and do not easily allow current to pass through. This inverse relationship is fundamental in understanding how different materials react to electric current and is critical for designing circuits and electrical systems. Other options focus on different relationships that don't describe the inverse property relevant to resistance. Current is influenced by voltage and resistance in Ohm’s Law, while capacitance refers to a capacitor’s ability to store charge rather than a property directly associated with resistance.
