Abohm (ab W)
Abohm (ab W) :
The abohm (symbolized ab Ω) is the unit of electromagnetic resistance in the cgs (centimeter/gram/second) system of units. It is equivalent to 10-9 ohm s. When a current of one abampere (1 abA) flows through a resistance of 1 ab Ω, the resulting potential difference across the component is one abvolt (1 abV). The abohm is an extremely small unit of resistance. In fact, an object with a resistance of 1 ab Ω would make an excellent electrical conductor. In practical applications, the ohm, the kilohm (k Ω) and the megohm (M Ω or M) are most often used to quantify resistance. For comparison, 1 ab Ω = 10-15 M Ω= 10-12 k Ω. The ohm (Ω) is the standard unit of resistance in the International System of Units (SI). Also See: Resistance, Ohm, Cgs or Small-Unit Metric System, and International System of Units (SI)
