Electricity Flashcards
1
Q
Static electricity
A
is a build up of electric
charge that can occur on good insulators e.g.
polythene and perspex rods
2
Q
Polythene rod
A
A polythene rod gains electrons if a woollen
cloth is rubbed on it (becomes negatively
charged)
3
Q
Perspex rod
A
A perspex rod loses electrons if it is rubbed by
a woollen cloth (becomes positively charged)
4
Q
Electric current
A
An electric current is caused by the flow of
electrons through a good conductor such
as a meta
5
Q
Conductors
A
Conductors are substances which allow
electric current to flow through them fre
6
Q
Insulators
A
Insulators are substances which do not
allow electric current to flow through them
