Ohm defines the unit of resistance of "1 Ohm" as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere, or 6.241×10^18 electrons. This value is usually represented in schematics with the greek letter "Ω", which is called omega, and pronounced "ohm".

WebMar 28, 2024 · The Ohm-metre is a composite unit which gives that the quantity whose unit is Ohm is multiplying the quantity (or set of quantities) whose end unit is meter in dimension. Formula used: In this solution we will be using the following formula; ⇒ G = 1 R where G is conductance, and R is the resistance. ⇒ ρ = R A L where ρ is the resistivity ... WebThe unit of the electrical resistance, measured with direct current, is the ohm (abbreviated Ω), named after the German physicist and mathematician Georg Simon Ohm (1789-1854). According to ohm’s law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it: R = U / I. Hence it follows: 1 Ω = 1 V/A.
