1
Q
LDR = bright light =
A
Low resistance
2
Q
What boosts electrons from valence band to conduction band ?
A
Light as it increase energy
3
Q
LDR conducts better=
A
Lower resistance
4
Q
Thermistor: thermal energy up =
A
Low resistance
5
Q
Thermal energy boosts electrons to the ?
A
Conduction band
6
Q
Thermistor conducts better =
A
Lower resistance
7
Q
In order to conduct electricity, solids need to have
A
Delocalised electrons
8
Q
How do delocalised electrons create electricity
A
By flowing through a solid causing an overall movement of charge ( current)
