What does the unit "ohm" measure in an electrical context?

• A. Voltage
• B. Current
• C. Resistance
• D. Power

Answer: (C)

The unit "ohm" is used to measure resistance in an electrical context. Resistance indicates how much an object opposes the flow of electric current. When a voltage is applied across a conductor, resistance determines how much current will flow according to Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R), or V = IR. The higher the resistance measured in ohms, the less current will flow for a given voltage. Understanding resistance is fundamental for anyone working with electrical systems, as it affects circuit design, load calculations, and overall system performance. This unit is essential in various applications, from designing simple circuits to complex electrical systems in entertainment technology.
