In what unit is resistance measured?

Resistance is measured in ohms, which is the unit that quantifies the opposition to the flow of electric current in a circuit. Specifically, one ohm is defined as the amount of resistance that allows one ampere of current to flow when a voltage of one volt is applied across it. This relationship is articulated in Ohm's Law, which states that voltage (V) equals current (I) times resistance (R), expressed as V = I × R. Understanding the concept of resistance in ohms is fundamental for anyone working in electrical engineering or related fields, as it helps in analyzing and designing electrical circuits. Other units such as volts, watts, and amperes measure different aspects of electricity: volts measure electric potential, watts measure power, and amperes measure current.
