STATIC DISCHARGE-A SUDDEN FLOW OF STATIC ELECTRICITY FROM ONE OBJECT TO
ANOTHER
STATIC ELECTRICITY- THE BUILDUP OF NONFLOWING ELECTRIC CHARGE
VOLTAGE- THE DIFFERENCE IN POTENTIAL ENERGY BETWEEN TWO ENDS OF A
CIRCUIT
Chapter 8 Review Cont.
✦
Static electricity is the buildup of nonflowing charge. Static discharge is the
release or sudden flow of that charge to another object.
How does the picture show the following:
circuit-The wire is a component of the circuit that connects the ends of the battery
voltage-The two ends of the battery have a difference in
potential energy.
electric current-When the ends of the battery are connected
to the wire, the current flows through the circuit

Static Electricity
charge-property of a particle that causes it to attract or repel other particles
✦
static electricity-the buildup of nonflowing electric charge
✦
static discharge- a sudden flow of static electricity from one object to another
✦
Opposite charges attract each other
✦
same charges repel each other
✦
Protons are positively charged
✦
Neutrons are particles with no charge
✦
Electrons are negatively charged
✦
When an atom has the same number of protons and electrons, the opposite charges cancel each other out so
that the overall charge of an atom is neutral.
✦
atoms can be charged by gaining or losing electrons

current electricity- the continuous flow of electric charge through a material
✦
circuit-a complete path through which an electric current can flow
✦
voltage-the difference in potential energy between two ends of a circuit
✦
current electricity can flow through different types of metal. Therefore, these metals are good conductors
✦

✦
For electricity to flow continuously it must travel through an unbroken circuit. (LIGHT AND BATTERY

Circuit Types
✦
resistance- a measure of how difficult it is for current electricity to flow
✦
series circuit-a circuit with a single path for an electric current
✦
parallel circuit-a circuit with more than one path for an electric current
✦
As resistance increases, the amount of current decreases
Electromagnetism
✦
ferromagnetic-relating to matter with strong magnetic properties
✦
electromagnet- a magnet that produces a magnetic field by means of an electric current
✦
Electromagnetism is magnetism produced by an electric current
✦
✦
In most atoms, electrons are paired . In some types of matter, atoms have unpaired electrons, which causes an
atom to ave magnetic properties
Producing Electricity
✦
generator- a machine that produces electricity from moving parts
✦
electrical energy can be transformed into other kinds of energy
