What does "Ohm" represent in an electrical circuit?

• A. Flow of electricity
• B. Pressure of the currents
• C. Resistance to current flow
• D. Voltage level

Answer: (C)

"Ohm" is a unit of measurement that represents resistance in an electrical circuit. More specifically, it quantifies how much a material resists the flow of electric current. According to Ohm's Law, which states that voltage equals current multiplied by resistance (V = I x R), understanding resistance is crucial for determining how electricity operates in various components of a circuit. In electrical terms, when a component has a higher resistance measured in ohms, it allows less current to flow through it for a given voltage. This is fundamental in designing circuits and selecting materials, as different components have varying resistance levels that affect overall performance and efficiency. Therefore, knowing that "Ohm" relates specifically to resistance helps in understanding the behavior of electrical systems.
