Electricity and Magnetism
Electricity
Static Electricity
Static electricity is a buildup of electric charges on objects
Friction
Friction is the force resisting
Charge
Positive
A positive charge is made when an Atom has more protons than electrons.
Negative
A negative charge is made when an Atom has more electrons than protons.
Static discharge
Static discharge occurs when something that is negatively charged encounters another metal. Then the object that is negatively charged repeals all the other electrons. When the object gets close to the metal the air between the objects becomes electricity charged which allows electrons to suddenly flow from one object to the other object.
Example #1
Rubbing a balloon across your hair
Example #2
Walking across a carpet and touching a metal door handle
Electric Field
An electric field surrounds an electric charge, and exerts force on other charges in the field, attracting or repelling them.
Test charge
A test charge is a charge with a magnitude so small that placing it at a point has a negligible affect on the field around the point.
Electric field Strength
A quantitative expression of the intensity of an electric field at a particular location.
Non-contact force
A non-contact force is a force which acts on an object without coming physically in contact with it
Circuits
An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, instructors and diodes, connected by conductive wires or traces through which electric current can flow.
Curent
An electric current is the rate of flow of electric charge past a point or region.
Ampers
the unit of electrical current
Voltage
Voltage is the pressure from an electrical circuit's power source
Resistance
Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it.
Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
types of circuits
Series
A circuit which the current follows one path
Parallel
A circuit which the current has two paths
