An electric circuit the closed path of electron flow from a current source. The point where the electrons first enter the circuit is known as the "source," while the point where they exit is known as the "return." The portion of the path between the source and the return is called the "load" of the electrical circuit. A simple electric circuit is one that only contains the minimum attributes required for the circuit to function. A simple electric circuit requires only three characteristics in order to work properly. The circuit must have a source, a conductive path, and a resistor. The source, which emits the electrons, is usually an electrical outlet or a battery. The conductive path must be a medium that can transfer the electrons and is typically some kind of wire. The resistor is any o
