Name Resistor
A resistor symbol stands for a component that opposes current. The zigzag (US style) and the plain rectangle (IEC style) are two drawings of the same component.
Fig. 2

Name Variable resistor
A diagonal arrow through the resistor body marks a variable resistor.
Fig. 3

Name Potentiometer
A potentiometer has three terminals: the two ends of the resistive track and a wiper, drawn as an arrow touching the body.
Fig. 4
12
Name Rheostat
A rheostat is a variable resistor used with two terminals: one end of the track and the wiper.

Name Thermistor
A thermistor's resistance changes with temperature. NTC resistance falls as temperature rises; PTC resistance rises. A generic thermistor symbol without a type label does not distinguish the two.

Name Light-dependent resistor
Two arrows arriving at a resistor body mark a light-dependent resistor (photoresistor).
