In a capacitive circuit - Study guides, Class notes & Summaries

BASIC ELECTRICAL ENGINEERING What is a load in a circuit? An electrical load is an electrical component or portion of a circuit that consumes (active) electric power. This is opposed to a power source, such as a battery or generator, which produces power. In electric power circuits examples of loads are appliances and lights. What is the load in electrical wiring? At the second device, the line is the power source coming in from the first device; the load is the wire going out to th...
