Stationary electrical charges and the forces that they exert
Is much stinger than gravity
Like charges repel unlike charges attract
law of charges
The net positive or negative charge is measured in?
The creation of a charged region on a neutral object when exposed to a nearby electrical charge is?
A neutral molecule whose electrons have shifted to from positive and negative ends or poles is?
Changes can be detected with what instrument?
Materials that offer little resistance to electron motion.
A loss of static charges.
A device used to protect buildings from lightning
The first capacitor
A devise that stores electrical charges
Electricity that involves continuously moving charges is called?
Most TVs contain a large vacuum tube screen called?
cathode-ray tube (CRT)
Electrons that have kinetic energy have?
electrical potential energy
The flow of positive charges through a conductor is called?
Current that flows in one direction is called?
The compleat path from the source of electrons to the end is called?
Something that electricity to some other useful form is called?
Allows you to open or close the circuit.
Consists of one or more electromechanical cells that supply electrons released by a chemical reaction.
Supplies electrons released by a chemical reaction.
We measure potential difference with a unit called?
The unit in which electrical current is measured.
The resistance to electrical flow is called?
What changes the voltage of the current in an electrical circuit?
Ohm's law state that.
As the size of the voltage changes the current is directly proportional the the voltage change, and the current is directly proportional to the resistance.
The unit that resistance is measured in.
The unit of electrical energy used by utilities to sell electricity.
