100
This controls an electric current through a circuit.
What is a switch?
100
This is the buildup of electrical charges on an object.
What is static electricity?
100
A coil of wire wrapped around an iron core can act as this.
What is an electromagnet?
100
These are materials that let charges flow through them easily.
What is a conductor?
100
Objects can be protected from lightning by doing this with a wire.
What is grounding?
200
This is electric current that rapidly changes directions.
What is alternating current?
200
This is an object in a circuit that resists the flow of electrons.
What is resistor?
200
This is a device that changes motion into electrical energy.
What is a generator?
200
This is formed when an electric current passes through an unbroken path of conductors.
What is a circuit?
200
This is the directions of the magnetic forces around a magnet.
What is magnetic field?
300
This is made of metal and allows electrical energy to pass through them.
What is a conductor?
300
This is a positively charged particle.
What is a proton?
300
This is a negatively charged particle.
What is an electron?
300
If a house had this all the lights would go out when one light is turned off.
What is a series circuit?
300
An electrician would use rubber gloves for this reason.
What is because rubber is an insulator?
400
These charges one another.
What are opposite charges?
400
This will be attracted to the south pole of a magnet.
What is the north pole of a magnet and anything made of iron?
400
Rubber, wood, glass are all these.
What are insulators?
400
When I plug in my radio this is happening.
What is changing electrical energy to sound energy?
400
Seven light bulbs are connected to one electrical circuit. When one bulb burns out the others continue to light up.
What is a parallel circuit?
500
This turns current off and on.
What is a switch?
500
Magnetic field lines are said to point in this direction.
What is north to south?
500
This is when an object shares its excess charge with a much larger conductor.
What is grounding?
500
Where magnetic field lines are the strongest.
What is at the poles?
500
Batteries are an example of this.
What are voltage sources?
