An electrical circuit is a conductive path through which electrical current can flow. A basic electrical circuit is made up of four types of components: power source, load, conductors, and the controller.
Electrical power is the rate at which electrical energy is consumed by a load in an electrical circuit.
This module will describe the function of each of the elements of a circuit and the relationship between voltage, current, and resistance, which is defined by Ohm's law. The definition and calculation of electric power will also be covered.
