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)
- 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
- Where the resistance
changes with temperature
- LDR
- A light dependent resistor
- A resistor whos resistance changes at differnt light levels
- A light dependent resistor
