Detailed explanation-1: -The Volt V, Ampere A, and Ohm are the standard units of electrical measurement for voltage, current, and resistance, respectively.
Detailed explanation-2: -The unit of the electrical resistance, measured with direct current, is the ohm (abbreviated ), 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.
Detailed explanation-3: -Resistance can be calculated by measuring the current and voltage using Ohm’s Law. As a result, a circuit’s resistance value can be determined if the current and voltage measured values are known. Analog multimeters and digital multimeters employ the measurement principle of Ohm’s Law to measure resistance.
