Thermistor and LDR

What it is for

Sensors: a thermistor’s resistance falls when hot, an LDR’s in light.

Mistake to avoid Thinking resistance rises with temperature or light: for an NTC thermistor and an LDR it falls.

Drawn in ink: the site's lab kit has no model of it yet, so the one at school may look a little different.
