|
|
What is electrical charge |
Electricity is the result of electrical charges. An electrical charge is a property of matter (like a color or hardness |
|
|
What is matter made up of? |
tiny particles called atoms |
|
|
What is inside an atom? |
An atom consists of the tiniest particles that have both a positive and negative electrical charges. |
|
|
A positive and negative charge _________ each other. |
attracht (pull) |
|
|
Like charges _______ each other. |
repel (push away) |
|
|
What is static electricity |
The buildup of electrical charges on an object |
|
|
How do charges move? |
They move by Electrical Discharge, Lightning, Electric current. |
|
|
What do you need to make an electric current? |
You need a path that will carry it. |
|
|
what is the path along which an electric current flows called? |
Circuit |
|
|
Name the 3 parts of a Simple Circuit |
Power Source A source powers a load Connectors carry electrical charges between the power source and the load |
battery lightbulb or a motor wires |
|
What is the flow of electrical charges through a circuit called |
current electricity |
|
|
I order for the current to keep moving, there can not be any _______________. |
gaps or breaks in the circuit |
|
|
What is a complete, unbroken circuit called |
closed circuit |
|
|
A circuit wit gaps is called an |
open circuit |
|
|
The path in an _________ circuit is incomplete & the current will not flow through it. |
open |
|
|
Having an open switch means the circuit is open. What does it do to the current? |
No current flows = Lights are off |
|
|
A switch in a closed position means a complete circuit. What does it do to the current? |
Current flows through it = Lights are on. |
|
|
A one-way circular path that travels in one direction is called |
series circuit |
|
|
In a series circuit, electric current flows in the _____________ along a single path.
|
same direction |
|
|
In order for electrical charges to flow in a series circuit, the parts much be ________. |
connected to each other |
|
|
Charges do not flow through a series circuit when one part is _________. |
removed. |
|
|
Circuit that leads to the same place, but takes different paths is called? |
parallel circuit |
|
|
Different paths in a circuit are called? |
branches
|
|
|
In a parallel circuit, if you remove one part, current still flows through the _______________ in the other branch. |
complete circuit |
|
|
Electric outlets in most homes are connected to ________ circuits. |
parallel |
|
|
A ____________ circuit turns off all electrical devices in a home at once. |
series |
|
|
How do material affect the flow of electric current? |
Materials that allow current to flow through them are called conductors |
|
|
___________ do not allow current to flow through them? |
Insulators. They protect you from getting shocked |
|
|
What material is an example of an insulator? |
Plastic |
|
|
What is the ability to oppose or slow electric current? |
Resistance |
|
|
What will occur if a current flows through a path with little resistance? |
a short circuit can occur. |
|
|
How can short circuits be dangerous? |
The wires can heat up and cause a fire. |
|
|
What helps prevent short circuits? |
a fuse |
|
|
What protects a circuit breaker? How? |
A switch When a dangerously high current flows through it, the switch opens and current can not flow. |
