What is the SI unit of electrical resistance?

Explanation:
Resistance measures how strongly a component opposes current flow. In SI units, that opposition is quantified in ohms (Ω). One ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt, applied to those points, produces a current of one ampere, which means 1 Ω = 1 V / 1 A. This ties directly to Ohm's law, V = IR, linking voltage, current, and resistance. The ampere is the unit of current, the coulomb is a unit of electric charge, and the henry is the unit of inductance, so they describe different electrical quantities.
