????????
100
the 3 ways that an object can become charged.
What is induction, conduction, friction
100
The area surrounding a charged object
What is electric field
100
How electrical potential energy is measured.
What is volts
100
A complete, unbroken path for an electrical current
What is a closed circuit
100
When objects push each other away
What is repel
200
This happens when two objects rub together
What is charging by friction
200
The attraction and repulsion between charged objects.
What is electric force
200
the flow of electric charges
What is current
200
A circuit that has only one path for the current to travel. An example of this is a set of Christmas lights.
What is a series circuit
200
A circuit will not work if one part of the path is...
What is removed
300
This happens when a charged item rearranges the charges in a neutral object without touching it.
What is induction
300
Positively and negatively charged items are
What is attracted to each other
300
How easy or hard it is for electricity to flow through a material
What is resistance
300
A circuit with more than one path for the current to travel
What is a parallel circuit
300
This is done as current travels through wires
What is work
400
This happens when a neutral object is touched with a charged object.
What is charging by conduction
400
This happens when an electron is added to an atom.
The atom has a negative charge.
400
An electrical device that is connected so that it makes a path for electric charges to move
What is circuit
400
When an alternative path is created for a current
What is a short circuit
400
This does not allow electric charges to move freely. An example is the plastic or rubber on the outside of an electric cord.
What is an insulator
500
This type of particle produces an electric field.
What is charged
500
Why is an electric cord metal on the inside and plastic on the outside?
The metal wires on the inside allow current to move freely. The plastic on the outside does not allow the current to escape.
500
An object's resistance depends on these 4 things
What is thickness, length, temperature, and what it's made of
500
These 3 parts make up a circuit
What is voltage source (battery), load (light bulb), and wires
500
How does a fuse work
A fuse melts when too much current runs through a circuit. This opens the circuit and prevents a fire from starting.
