Circuits

1. LED Emits red, green, or blue light when electricity flows through it. Allows electricity to flow in only one direction
3. – the positive(+) electrode of a polarized electrical component through which current enters
7. a tool used for creating temporary electronic prototypes and experimenting with circuit design.
9. Emitting Diode semiconductor light source that emits light when current flows through it. Allows electricity to flow in only one direction
10. Used to resist the flow of electrical current. The amount of resistance can be adjusted using the screw on top.
11. allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
12. Turns electrical signal into a sound, usually a single buzzing tone.

1. an electrical component that restricts the passage of electrical current. Colored strips show its fixed resistance value
2. a device that converts chemical energy into electric energy
4. – the negative (-) electrode of a polarized electrical component through which current exits
5. used for the transmission of electricity or electrical signals in a circuit. Typically made of aluminum or copper and can be either bare or insulated.
6. Can absorb energy and store it temporarily. Provides electricity like a battery.
8. Used to resist the flow of electrical current. Resistance changes depending on how much light it receives.
