Action and use of circuit components
What this topic asks you to be able to do
- Describe how light-dependent resistors and negative temperature coefficient (NTC) thermistors work, and explain how they are used as input sensors
- outline how a variable potential divider operates
- Recall and apply the equation R1/R2 = V1/V2 for a pair of resistors acting as a potential divider
