WebThis article discusses resistance along with the resistance formula and its derivation. Resistance refers to the amount that an object impedes or resists in an electric current. … 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.
