New doubts,i hope anyone can help me,as from the IGCSE syallbus:
1.Describe compressions and rarefactions.
2.Give an account of charging by induction
3.Recall and use simple electron model to distinguish between conductors and insulators(easy things made hard :S )
4.What are relays and capacitors used for(other than storing energy)
5.Describe the action of a transistor as an electrically operated switch and show understanding of its use in switching circuits.
6.Recognize and show understanding of circuits operating as light sensitive switches and temperature operated alarms(using a relay or transistor)
7.Explain and use the terms analogue and digital.
and the whole 4.5 section except c.
Hope anyone can help,and thanks
