An electric circuit is a system of interconnected elements that allows the flow of electric current.
It consists of energy sources, such as a battery or a power supply, conductors that carry the current, such as wires, and control elements, such as switches and resistors.
Electric current flows through the circuit in a closed path, following the direction established by the connection of the elements. Electric circuits are used in numerous devices and systems, from appliances to lighting systems, and are fundamental in our daily lives.
