100
This is what unlike charges do (positive and negative for example)
What is attract?
100
A material through which charge can flow easily.
What is a conductor?
100
A combination of two or more electrochemical cells in a series.
What is battery?
100
The law that says that the resistance is equal to the voltage divided by the current.
What is Ohm's Law?
100
1000 watts
What is a kilowatt?
200
The build up of charges on an object
What is static electricity? *must have both words
200
The continuous flow of electricity through a material
What is electric current?
200
A device that transforms chemical energy to electrical energy. It contains electrodes in an electrolyte.
What is an electrochemical cell?
200
Electricity has only one path for current to take.
What is a series circuit?
200
A device that contains a thin strip of metal that melts when too much current goes through it. These are not reusable.
What is a fuse?
300
One way of gathering a charge that involves rubbing. Example: Electrons are rubbed from the carpet to your sock.
What is friction or charging by friction?
300
The complete, unbroken path through which electric charges can flow.
What is an electric circuit?
300
Voltage comes from a chemical reaction between this and the electrode in an electrochemical cell.
What is an electrolyte?
300
Different parts of the circuit are on different branches.
What is a parallel circuit?
300
A device that has a metal band that bends away from the wires, disrupting the current. This can be reset and reused.
What is a circuit breaker?
400
The loss of static electricity, lightning is an example.
What is static discharge?
400
The potential difference that causes a current in an electric circuit. This is the amount of force pushing an electric circuit.
What is voltage?
400
This is what causes voltage in a battery. It makes one electrode negative and the other electrode positive and that's how they have voltage.
What are chemical reactions?
400
This is the type of circuit that experiences a decrease in resistance when you add a light bulb.
What is a parallel circuit?
400
This is calculated by multiplying power by time.
What is energy?
500
A way of obtaining a charge with direct contact. Example: Electrons from your sock touches your skin, making your foot negative in charge.
What is conduction?
500
The easiest way possible. This is the path that electricity always takes. Explains how a bird can perch on an uninsulated electric fence.
What is the path of least resistance?
500
He was credited with the first battery though artifacts indicate early Egyptians may have had batteries.
Who is Alessandro Volta?
500
A device used to measure current.
What is an ammeter?
500
This is calculated by multiplying voltage by current.
What is power?
