Combine these according to how the components are connected: Resistors in series (connected end to end along one wire) can be added together. The total resistance R = R 1 + R 2 + R 3 ...
WebLater, more accurate measurements revealed that this current is 0.999 85 A. Since power is defined as the product of current and voltage, the ampere can alternatively be expressed in terms of the other units using the relationship I = P / V , and thus 1 A = 1 W/V. Current can be measured by a multimeter , a device that can measure electrical voltage, current, and …
