What is the basic electrical unit that measures a material's resistance to electric flow?

• A. Watt
• B. Volt
• C. Ohm
• D. Ampere

Answer: (C)

The basic electrical unit that measures a material's resistance to electric flow is the ohm. In electrical terminology, ohms quantify how much a material resists the flow of electric current. According to Ohm's Law, the relationship between voltage, current, and resistance is described by the formula: Voltage (V) = Current (I) x Resistance (R). Thus, the higher the resistance (measured in ohms), the less current will flow for a given voltage. Understanding ohms is crucial in various applications, including those within water distribution systems where electrical components might be used, such as pumps and sensors, to ensure efficient operation.
