variable resistor - can alter resistance in a circuit - useful for controlling volume, dimmer switch, etc
Components and Graphs
Straight line - current through a resistor - directly proportional to the potential difference across a resistor
Straight then curved - current through a diode -only flows in one direction because it has a very high resistance in the other direction
Curved - resistance of a bulb/filament lamp - increases as the temperature of the filament increases
