## What is the base unit of Ohm?

• Related Questions More Answers Below. Ohms is a unit of electrical resistance. In the “Ohm’s Law” equation (V = I*R), V is voltage (in Volts), I is current (in Amperes ), and R is resistance (in Ohms). Kilo-Ohms is simply a prefix of a factor of 1000 to the standard base unit of Ohms. So if we say that a resistor has 4 Kilo-Ohms of resistance, it has 4,000 Ohms of resistance.

## How much does 1 ohm equal?

• The SI derived unit for electric resistance is the ohm. 1 ohm is equal to 1.0E-9 gigaohm. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between ohms and gigaohms.

## What does ohm the practical unit of resistance?

• Ohm , abbreviation Ω , unit of electrical resistance in the metre-kilogram-second system, named in honour of the 19th-century German physicist Georg Simon Ohm .It is equal to the resistance of a circuit in which a potential difference of one volt produces a current of one ampere (1Ω = 1 V/A); or, the resistance in which one watt of power is dissipated when one ampere flows through it.
