Law of Electric charges |
like charges repel and opposites attract |
|
|
Electric forces |
the force between charged objects |
|
|
conduction |
transfer of electrons from one object to another by direct contact |
|
|
induction |
charges in an undercharged object are rearranged without direct contact with a charged object |
|
|
insulator |
charges can not move easily through because electrons are tightly bonded to the atom and are mot free to move |
|
|
static electricity |
build of electric charges on an object |
|
|
electric discharge |
the loss of static electricity as charges move off an object |
|
|
cell |
a device that produces an electric current by converting E into electric E |
|
|
battery |
converts chem. E into electrical E and is mode of several cells |
|
|
potential difference |
E per until discharge and is expressed in volts |
|
|
thermocouple |
converts thermal differences into electrical E and is used in furnaces and ovens |
