Electricity
Electricity is the form of energy that results from the interaction of charged particles, such as electrons and protons.
-
Static caharge(static electricity)
An electric charge thta tends to stay on the surface of an object, rather than flowing away quickley.
-
Charging by friction
Charging by friction is the process in which objects made from different materials rub against each other, producing a net static charge on a object.
-
Elecrostatic series
A list of materials that have been aranged according to their ability to hold on to electrons.
-
Insulator
A material in which electrons cannot move easily from one atom to another. Ex:Wood
-
Conductor
A conductor is a material in which materials can move easily between atoms. Ex: Metal
-
Semiconductor
A material in which electrons can move fairley well between atoms.Ex: Silicon
-
Ground
An object that can supply a very large number of electrons to, or can remove a very large number of electrons from, a charged object, thus nutralizing that object.
-
Electroscope
A device for detecting the presence of an electric charge.
-
Charging by contact
Generating a net charge on a neurtral object by touching it with a charged object.
-
Laws of electric charges
Laws that describe how two objects interact electically when one or both are charged.
-
Electric field
A property of space around a charged object, where the effect of its charge can be felt by other objects.
-
Inducing charge seperation
The movement of electrons in a substance, caused by the electric field of a nearby charged object that is not in direct contact with the substance.
-
Ion
A positively charged or negatively charged atom or group of atoms.
-
Lightining rod
A metal sphere or point that is attached to the highest part of a building and connected to the ground.
-
Electrostaic precipitator
A type of cleaner that can remove unwanted waste particles and liquid droplets from a flow of gas.
-
Van de Graff generator
A device that accumualates very large charges.
-
Radiation dosimeter
A small device that detects and measures exposer to radiation.
