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. WebI = E R = 4.5V 45Ω =0.10A I = E R = 4.5 V 45 Ω = 0.10 A. Since the meter movement passes 1.0 mA at full scale, the shunt current must be 99 mA.
