Electric Current And Simple Circuits
An electric circuit is a closed loop with a continuous flow of electric current from the power supply to the load.
Electric current and simple circuits. All electric circuits have one thing in common they transform electric energy to other forms of energy. A closed or complete path in which an electric current travels is an electric circuit. The si unit of electric current is the ampere or amp which is the flow of electric charge across a surface at the rate of one coulomb per. Electric circuits like ac lighting circuit battery charging circuit energy meter switch circuit air conditioning circuit thermocouple circuit dc lighting circuit multimeter circuit current transformer.
The simplest complete circuit is a piece of wire from one end of a battery to the other. Circuits are driven by flows. Flows are ubiquitous in nature and are often the result of spatial differences in potential energy. All electric circuits must contain a power source such as a battery.
An electric current flows in a closed path to and from a source of electric energy. Here are ten simple electric circuits commonly found around the home.
