Resistors
Calculated using OHM'S Law
Potential difference across a component is directly proportional to the current through it
V = I x R
- V=p.d (v) I=current (a) R=resistance (ohms)
Thermistor
- Where the resistance changes with temperature
- Low temp --> high resistance High temp --> low resistance
- At a particular temperature, a thermistor is an ohmic resistor
- used to: act as a thermometer, control circuits activated by temperature
LDR
- A light dependent resistor
- A resistor whos resistance changes at differnt light levels
