Answer:
Step-by-step explanation:
An electric circuit is an unbroken path along which an electric current exists and/or is able to flow. A simple electrical circuit consists of a power source, two conducting wires (one end of each being attached to each terminal of the cell), and a small lamp to which the free ends of the wires leading from the cell are attached.
When the connections are made properly, the circuit will “close” and current will flow through the circuit and light the lamp.
Once one of the wires is removed from the power source or a “break” is made in the flow, the circuit is now “open” and the lamp will no longer light.
In practical application, circuits are “opened” by such devices as switches, fuses, and circuit breakers. Two general circuit classifications are series and parallel.
The elements of a series circuit are connected end to end; the same current flows through its parts one after another.
