The megohm (1,000,000 ohms) and the milliohm (.001 ohm) are units derived from the ohm.Ohm the unit of electric resistance in the International System of Units (SI). It is named in honor of the German physicist G. S. Ohm. The international symbol is Ω. One ohm is the resistance of a conductor between whose terminals a voltage of 1 volt arises when a current of 1 ampere is flowing through the conductor. The relationship between the ohm and the other units of electrical resistance is as follows: 1 Ω = 1.11 ×, 1012 cgs electrostatic units = 109 cgs electromagnetic units. ohm[ōm] (electricity) The unit of electrical resistance in the rationalized meter-kilogram-second system of units, equal to the resistance through which a current of 1 ampere will flow when there is a potential difference of 1 volt across it. Symbolized Ω. ohmThe unit of electrical resistance of a conductor such that a constant current of 1 ampere in it produces a decrease in voltage across it of 1 volt.ohm the derived SI unit of electrical resistance; the resistance between two points on a conductor when a constant potential difference of 1 volt between them produces a current of 1 ampere.
Ohm Georg Simon . 1787--1854, German physicist, who formulated the law named after him Ohm (unit)The MKS unit of electrical resistance. One Ohm isthe resistance of a conductor across which a potential difference of one Volt produces a current of oneAmpere. Named after Georg Simon Ohm.ohmThe unit of measurement of electrical resistance in a material. One ohm is the resistance in a circuit when one volt maintains a current of one amp. The symbol for ohm is the Greek letter omega. See impedance.
Ohm's Law
The equation "R=V/I" is the more streamlined version of the one developed by German physicist Georg Simon Ohm in 1827. Ohm's law is used to calculate the resistance in materials such as metal, which maintain a linear relationship between voltage and current. In addition, Ohm's formulas, which are derived from Ohm's Law, are used to calculate voltage and current if the other two measurements are known.
OHM'S LAWwResistance = voltage divided by current R = V / I or R = E / I OHM'S FORMULASVoltage = current times resistance V = I * R or E = I * R Current = voltage divided by resistance I = V / R or I = E / R V or E = voltage (E=energy) I = current in amps (I=intensity) R = resistance in ohms Electric PowerPower in watts = voltage times current P = V * I ohm
