100
This is the type of current that runs in your house
What is alternating current (AC)?
100
Amps (Ampheres) measure this.
What is the flow of electricity?
100
The 3 things needed to make a circuit.
What are source, wire (conductor) and device (load)?
100
This type of rock is a natural magnet.
What is magnetite?
100
A material that stops the flow of electrons.
What is an insulator.
200
The current that flows from a battery.
What is direct current (DC)?
200
An electric circuit
What is a closed path in which an electric current can flow
200
When the light is switched on, you have this type of circuit.
What is a closed circuit?
200
This happens when you put the north pole of one magnet towards the south pole of another magnet.
What is they attract?
200
This is the reason copper wires are used to transfer electricity.
What is because metal is a good conductor of electricity?
300
The type of current that flows through power lines.
What is alternating current?
300
This is the result of a large discharge of static electricity.
What is lightning?
300
This type of circuit resembles a loop for an electric current to flow. If one bulb is removed the other bulbs will stop working.
What is a series circuit?
300
The 3 types of metal that can be magnetized.
What are iron, nickel, and cobalt?
300
This is a material somewhere between a conductor and an insulator. A lightbulb filament is one.
What is a resistor?
400
Opens and closes to allow current to flow in a circuit
What is a switch?
400
MRI stands for this.
What is Magnetic Resonance Imaging?
400
A parallel circuit differs from a series circuit because it has this.
What is an alternate path for electrons to flow?
400
The 3 things you need to make an electromagnet.
What are a battery (power source), wire (conductor) and iron core?
400
Electrical energy can be transformed into these four forms of energy
What are light, sound, heat, and mechanical?
500
Seven forms of energy.
What are chemical, light, heat, mechanical, nuclear, electrical, and sound
500
This is wherer the electrical energy from an outlet gets it's original energy (most of the time)
What is chemical energy from fossil fuels which powers a generator at a power plant?
500
Mechanical energy is transformed into electrical energy in this device.
What is a generator?
500
This uses an electromagnet to transform electrical energy to mechanical energy.
What is an electric motor?
500
a group of atoms that have their magnetic poles pointing in the same direction
What is magnetic domain?
