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?
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?
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.
What are nails, paperclips, and aluminum foil? (Anything metal!)
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 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?
These are some examples of insulators.
What are plastic, wood, and rubber? (There are many other examples!)
This is the unit used to measure the energy used by an appliance (like a microwave) in a certain amount of time.
What is a watt?
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 person invented the light bulb.
