Working Together
Shocking!
100
Two objects that have different charges do this.
What is attract or pull toward each other?
100
A circuit that connects several objects one after another so that the current flows in a single path.
What is a series circuit?
100
Anything that pulls iron, steel, and certain other metals.
What is a magnet?
100
Electricity and magnetism are this to each other.
What is closely linked?
100
Two charges that are the same will do this.
What is repel or push away from each other?
200
A measure of how much a material opposes the flow of electric current and changes electric current into heat energy.
What is resistance?
200
If you plug to many appliances to an outlet you can cause this.
What is an overload?
200
A rock that is magnetic.
What is a lodestone?
200
A machine that uses an energy source and a magnet to make electricity.
What is a generator?
200
Electric current passes only through these?
What are conductors?
300
Electric currents is the flow of this.
What is negative charges through matter?
300
If each appliance or light has its own electrical path, it is this.
What is a parallel circuit?
300
Like poles will do this.
What is repel or push away from each other?
300
Name two objects that use electromagnets.
What is a fan, doorbell, or telephone?
300
Generators have huge electromagnets with huge coils of wire and magnets. Their power source comes from this that move the magnet and make electricity.
What are nuclear energy or coal?
400
Plastic and rubber is a good example of this for electricity.
What are insulators?
400
Frayed or broken insulation is dangerous because it can do this.
What is cause a fire or electric shock?
400
A magnets force is greatest here.
What is at the poles?
400
This is created when electric current flows through a wire.
What is an electromagnet?
400
If you picked up negative charges and touch a light switch, this happens.
What is negative charges jump from you to the switch and you will get shocked?
500
Electric current will flow through a circuit as long as the path is this.
What is unbroken or closed?
500
Water is a good this for electricity.
What is conductor?
500
The northern lights are caused by this.
What is Earth's magnetic field?
500
The scientist that realized that electricity and magnetism are linked.
Who is Hans Christian Oerstad?
500
Most electric generators make electricity using these two things.
What is a magnet and an energy source?
