Electric Circuits Vocabulary
Term | Definition |
---|---|
Circuit | A way of routing electricity along a path |
Electricity | This happens when electrons move from one place to another |
Electrons | Negatively charged particles of an atom |
Static Electricity | Not a useful power source as all the energy is released at once |
Static Electricity Example | Lightning, or a shock from your sibling |
Current | A steady flow of electricity, it needs a path to follow |
Power Source | Where electricity comes from for a device or TV |
Power Source examples | Wall outlet or a battery |
Negative Terminal | The flat side of the battery, electrons leave from here |
Hot Slot | On a wall outlet, it is the smaller slot |
Conductor | Any material that allows electrons to move through it easily |
Conductor Examples | Copper, gold, silver or most metals |
Copper Wire | We use this as the conductive core of insulated wires as it is cheaper than gold or silver |
Insulator | These materials are hard for electricity to move through |
Insulator examples | Rubber, plastic, ceramic or glass are examples of these |
Load | The device that uses the electricity along a circuit, electrons flow through them to make them work. Like a lamp or fan. |
Positive Terminal | Electrons flow back into this at the end of a circuit, the bump on the end of a battery. |
Neutral Slot | The tallest slot on a wall outlet, where the electrons flow back into the wall |
Switch | This controls whether a circuit is on or off. |
Open Circuit | This makes a circuit go OFF |
Closed Circuit | This makes the circuit go ON |
