The resistance R of a uniform cylinder of length L, of cross-sectional area A, and made of a material with resistivity ρ, is (8.4.1) R = ρ L A. The table below gives representative values of ρ.
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. WebHow Earth Resistance is Measured by Editorial Staff The term “earth resistivity” expressed in ohm-centimeters (abbreviated ohm-cm) is one basic variable affecting resistance to earth of an electrode system. But the actual value of earth resistivity need not be measured to check the electrode earth resistance.
