Electricity Everything in the world is made up of  atoms.   Each  atom has smaller parts in it.  One of those parts is  called  electrons.   Electrons can move from atom to  atom.  When an electron moves to a different atom, it  causes another electron to have to move.  When  electrons move quickly from one atom to another is it  called  Electricity!

Inside an atom,  electrons have a  negative charge  and protons  have a  positive  charge.   These  particles  attract  each other. charge  is a measure  of the extra positive  or negative particles  that an object has.

Unformatted text preview: electric current. A current will move along a wire or a path called a circuit. Circuit means to “go around.” Circuits • A series circuit is a circuit that has only one path for the current. • A parallel circuit has more than one path for current to travel. • Lights in our homes are wired in parallel circuits. Conductor • A conductor is a material that current can pass through easily, like metals. Resistor • A resistor is a material that resists, but doesn’t stop the flow of current. Insulator • An insulator is a material that current cannot pass through easily, like plastic. Electric Cell • An electric cell supplies energy to move charges through a circuit, like a battery....
