Static 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
• A polythene rod
A
gains electrons if a woollen cloth is rubbed on it (becomes negatively charged)
3
Q
A perspex rod
A
loses electrons if it is rubbed by a woollen cloth (becomes positively charged)
4
Q
• An electric current
A
• An electric current is a flow of Electric charge
5
Q
Conductors
A
• Conductors are substances which allow electric current to flow through them freely
6
Q
Insulators
A
Insulators are substances which do not allow electric current to flow through them
