Opposite charges attract each other with an electric force
like charges repel with an electric force
Coulombs Law
like charges repel and opposite charges attract
objects have an electric force proportional to the absolute value of the product of the charges and inversely proportional to the square of the distance between them
Electrostatic Induction
a method to create or generate static electricity in a material by bringing an electrically charged object near it
Causes the redistribution of electrical charges which creates a polar object (charged sides with net charge of zero)
insulators
fixed position of charges
Electrostatic Conduction
When a charged object comes in contact with a neutral object and spreads the charge
the amount of work needed to move a unit of positive charge from a reference point to a specific point inside the field without producing an acceleration
Voltage
an electromotive force or potential difference with units as volts
Good overall explanation of Voltage, Electric charge, and electric potential
Practice Problems for Voltage, Electric charge, and electric potential
Circuits
Circuits
a path between two or more points along which an electrical current can be carried
Basic circuit information
How to solve circuit problems with resistors
Ohm's Law
Voltage (V)
Potential energy difference
Current (I)
A measurement of the flow of charge (how much is flowing)
Resistance (R)
the measurement of the difficulty for charges to flow
Resistivity
the property of materials that causes it to resist flow of charges
High resistivity
very little charge flowing through
Low resistivity
almost all of the charge flowing through
Depends on the material of an object and temperature
