A
semiconductor
2
Q
as you increase heat or light intensity the (1)
A
- Ions vibrate faster
3
Q
as you increase heat or light intensity the (2)
A
- Electrons released from atoms of the semiconductor to produce a higher current
4
Q
what are the graphs for both LDRs and thermistors
A
resistance decreases as temp/light intensity increases
