Electricity and Magnetism
Electricity
Static Electricity
Friction
rubbing together of two objects, causes an imbalance of electrons by transferring electrons from one object to another.
Static discharge
occurs when the discharge of electrons is the spark you see and the shock you feel.
charge
positive
the state of having a deficiency of electrons; having a higher electric potential
negative
having a surplus of electrons; having a lower electric potential
picture did not work
rubbing balloons on your neck. sloshing fuel in tank, pipes
the buildup of electric charges on objects.
fields
Electric Field Strength
is a quantitative expression of the intensity of an electric field at a particular location
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.
picture is on other paper
non-contact force
A non-contact force is a force which acts on an object without coming physically in contact with it
is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge or a negative test charge
circuits
Voltage
is electric potential energy per unit charge, measured in joules per coulomb ( = volts
Resistance
The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it
current
ampers
is a closed loop that electrons can travel in
is a closed loop that electrons can travel in
Electromagnet
is a type of magnet in which the magnetic field is produced by an electric current. usually consist of wire wound into a coil.
is a closed loop that electrons can travel in
types of circuits
