static electricity
|
it is the result in an imbalance between positive and negative charges on the surface of an object
|
|
electrostatics
|
the study of static electricity
|
|
neutral object
|
an object where there are the same number of positive and negative charges
|
|
negatively charged object
|
an object where there is more electrons then protons
|
|
positively charged object
|
an object where there is more protons then electrons
|
|
charge separation
|
this is when the charge from an object is repelled by another obeject and the charge from that object is separated throughout the whole entire object
|
|
why do negative charges move and positive charges dont?
|
This is because electrons have less of a mass and they are further away from the nucleus
|
|
charging by contact/conduction
|
this happens when electrons move from one object to a neutral object
|
|
charging by induction
|
this is when you use a charged object to charge a neutral object without touching
- electrons repel from each other sending |
|
charging by friction
|
When two objects are rubbed together and they become charged because electrons travel from one object to the other.
|
|
laws of electrostatics
|
1) like charges repel
2) opposite charges attract 3) some neutral object are attracted to charged objects |
|
conductors
|
Conductors allow electricity to flow through them
|
|
insulators
|
they prevent electrical flow
|
|
current electricity
|
the flow of electric charge
|
|
electric circuit
|
an electrical device that provides a path for electrical current to flow
|
|
load
|
a component of a circuit that converts electricity
|
|
control device (switch)
|
a component of a circuit that can be switched on or off in order to stop or continue electrical flow
|
|
connectors
|
it links to things together
|
|
series circuit
|
An electric circuit connected so that current passes through each circuit element in turn
|
|
parallel circuit
|
An electric circuit in which the elements, branches (having elements in series), or components are connected between two points, with one of the two ends of each component connected to each point.
|
|
source
|
this is where the electricity come from
