The flow of tiny particles called electrons
Electrons flowing in a closed path flow in this
Energy supplied by electromagnetic radiation
A periodic conduction current that reverses its direction at regular intervals
An electrical current flowing in one direction only
One of two terminals of an electric cell, battery or generator; one is designated positive and the other negative
A unit of power or work of one ampere of electric current under pressure of one volt
A unit of electromotive force which, when applied to a conductor whose resistance is one ohm will produce a current of one ampere
materials that don't let electricity go through them
materials that let electricity go through them
A series circuit allows electrons to follow only one path. The loads in a series circuit must share the available voltage. In other words, each load in a series circuit will use up some portion of the voltage, leaving less for the next load in the circuit. This means that the light, heat, or sound given off by the device will be reduced.
the electric current can follow more than one path to return to the source, so it splits up among all the available paths.
metals are good conductors
this word means "go around"
Why don't you get electricuted in a bumper car?
Because you don't touch the source of the electricity at the top of the rod

There is enough electricity coming out of the wall to do what to you?
stop your heart and burn you
How does an electric train run?
There is a circuit inside the train track
Which scientist took a coil of wire and moved it over a magnet to cause electricity?
What does the solar electric hybrid car run on?
Electrons jump from what to what?
one atom to another
Something that lets only some of the electrons pass through
In an electrical circuit the pressure is referred to as this
In an electrical circuit the number of electrons is referred to as this

The goopy chemicals inside a battery
An electric eel can produce how many volts of electricity?
up to 800
What can move huge generators?
AC stands for
DC stands for
a cell that turns light into electricity
Why are there two prongs on every plug?
Because electricity has to travel in a circuit
