Circuits
This is the flow of electric charges that moves in an unbroken loop.
What is an electric current?
These are materials through which an electric current can pass.
What are conductors?
Early scientists most likely saw a discharge of electricity for the first time while observing this.
What is a lightning storm?
These are temporary magnets, NOT permanent magnets.
What are electromagnets?
In this type of circuit, electricity has only one path to follow.
What is a series circuit?
This is the pathway taken by an electric current.
What is a circuit?
These are materials through which an electric current CANNOT pass.
What are insulators?
These are three examples of non-renewable sources of energy.
What are coal, natural gas and gasoline?
This term means "to push away".
What is repel?
In this type of circuit, electricity has more than one path to follow.
What is a parallel circuit?
This type of circuit is a complete circuit where everything is connected and electricity can easily flow through it.
What is a closed circuit?
These are examples of conductors. (Hint: think of the experiment we did in class!)
What are nails, paperclips, and aluminum foil? (Anything metal!)
These are three examples of renewable sources of energy.
What are solar, hydro, and geothermal energy?
This is the invisible force field around every magnet.
What is a magnetic field?
This is a material that cuts down the flow of current, but does not stop it.
What is a resistor?
This type of circuit is an incomplete circuit where there is some part that is not connected and electricity cannot flow through it.
What is an open circuit?
This is the rate of flow of electrons and does not have anything to do with the energy of electrons.
What is electric current?
All magnets have these two types of poles.
What are north and south poles?
These are the basic materials needed to make a complete circuit.
What are a power source (battery or outlet), wires, and a light bulb?
This is a device that is used to open and close a circuit easily without connecting and disconnecting the wires.
What is a switch?
This is the name of the crackle you hear and feel when you touch a doorknob after rubbing your feet across a carpet.
What is static electricity?
This is the difference is energy of electrons between two different points in an electric circuit.
What is potential difference?
Like poles of a magnet interact this way
They repel?
These are two qualities of a material used as FUSE.
What is High Resistance & Low Melting Point?
