What is the typical unit of measurement for resistance?

• A. Volts
• B. Amperes
• C. Ohms
• D. Coulombs

Answer: (C)

The typical unit of measurement for resistance is Ohms. Resistance measures how much an object resists the flow of electric current, and Ohm is the standard unit named after the German physicist Georg Simon Ohm. In the context of an electric circuit, Ohm's law, which is represented by the formula V = IR (where V is voltage, I is current, and R is resistance), highlights the relationship between voltage, current, and resistance. This relationship makes it clear that resistance is inherently tied to current flow and voltage, and hence Ohms is the appropriate unit to quantify this property. The other units mentioned (volts, amperes, and coulombs) relate to different electrical properties. Volts measure electric potential or voltage, amperes measure electric current, and coulombs measure electric charge. Each of these plays a significant role in the study of electricity and circuits, but none serves as the correct unit of measurement for resistance.
