Electricity 1
Materials that allow electricity to move through it easily
Conductor
Materials that do not allow electricity to move through them easily
Insulator
What is the purpose of a switch
To switch the circuit from open to closed
Unlike poles of magnets do this.
attract
The name of the clips used to hold the wires in our circuits in class.
Plastic, glass, and rubber are good examples of
Insulators
what are three examples of power supplies for electricity
Battery, solar cell, generator
This circuit has one pathway
Series
What is formed when a wire carrying electricity is wrapped around an iron or steel object, like a nail.
electromagnet
This circuit has more than 1 pathway
Parallel
In this circuit, if one lightbulb goes out, the others will too
Series
What is the difference between an open circuit and a closed circuit
Closed - electrons can flow and circuit is working
Open - electrons cannot flow and circuit is not working
Parallel
What each end of a magnet is called.
magnetic pole
Anything that slows down of prevents movement of electrons through a conductor is called what?
resistance
In a series circuit, what will happen to the brightness of the lightbulbs if another lightbulb is added?
They will get dimmer
In series circuit, what will happen to the brightness of bulbs if one of lightbulbs was removed?
They will become brighter
Why is it in a series circuit, the more lightbulbs added the dimmer the bulbs get?
Because adding in more lightbulbs adds more resistance
The forcefield around an electromagnet is called this.
electromagnetic field
In a parallel circuit, what will happen to the brightness of the bulbs if either a lightbulb was removed or added in?
They will stay the same
chemical energy
In a complete circuit, what happens to the light bulb when the switch is opened?
The bulb goes off.
When the electricity reaches the filament inside the lightbulb, what is that energy transformed into?
Heat and Light Energy
This is what like poles of a magnet do.
repel
What happens to the resistance as the length of the wire increases
The resistance increases
