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.
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.
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
