WebOhm starts by describing a unit of resistance that is defined by current and voltage. So, let's start with voltage and go from there. Voltage. We define voltage as the amount of potential energy between two points on a circuit. One point has more charge than another. This difference in charge between the two points is called voltage. Webohm. As a unit of measurement, use ohm for technical writing, which can be plural. An alternative is the omega symbol (Ω). There should be a space between the number and the unit.
