Components
Circuits are composed of many components. Circuits can have many combinations of different items to accomplish different tasks. Every circuit needs an energy source, or battery, something to be powered, a light bulb for instance, and wires to connect these components. However, these are not the only possible components of circuits:
Switches:
Switches can provide an open or closed pathway for the energy source. When a switch is on, the pathway is closed, so energy can flow freely. When a switch is off, the pathway is open, and the energy cannot openly flow. A simple example of this is a light switch!
Resistors:
Resistors are used to filter the exact amount of energy needed in a circuit. Adding resistors to a circuit can help power items which require specific amounts of energy, and are therefore very helpful!
A flashlight is a good example of a circuit that uses a battery, a light bulb, a switch, and a resistor!
