What are the FOUR parts of a simple circuit?

switch, electric energy source (battery), electric device (lightbulb), electric conductor (wire)

TRUE/FALSE: A good conductor has little electric resistance so electric current can flow through it.

TRUE

TRUE/FALSE: TVs, computers and other appliances use alternating current.

TRUE

Most current used in homes and businesses is ___ current

alternating

electromagnetic radiation that can be seen

light

TRUE/FALSE: Flashlights use direct current.

TRUE

circuit in which there is only ONE path for the electric current to follow

series circuit

a definite quantity of electricity; can be positive or negative

electric charge

a measure of how difficult it is for an electric current to flow in a material

electric resistance

a machine that transforms mechanical energy to electric energy

generator

An electric motor in a circuit transforms electric energy to __ energy.

mechanical

How do electrons move through a battery?

Chemical reactions within a battery move electrons from one end of the battery (positive terminal) to the other end (negative terminal).
