What is the basic unit of resistance in electrical terms?

The basic unit of resistance in electrical terms is the Ohm. Resistance is a measure of how much an object opposes the flow of electric current. According to Ohm's Law, resistance can be understood as the ratio of voltage (the electric potential difference) to current (the flow of electric charge). The unit Ohm is defined as one volt per ampere, which highlights the relationship between these three fundamental electrical properties: voltage, current, and resistance.

Understanding resistance in terms of the Ohm is essential for analyzing and designing electrical circuits, as it helps determine how much current will flow in response to a given voltage. This concept is crucial for anyone working with electrical systems, as it forms the basis for understanding how circuits function, ensuring safety and efficiency in electrical applications. The other choices refer to different electrical concepts; the Volt is a unit of voltage, the Ampere is a unit of current, and the Watt is a unit of power, each playing distinct roles within the broader realm of electrical engineering.
