Symbols - Resistor Variable

Rheostat
It is a two terminal variable resistor. They are generally used to control the current in the circuit. Generally used in tuning circuits and power control applications like heaters, ovens etc
Preset
It is a mini variable resistor. It is also called Trimmer Resistor or Trim Pot. The resistance is adjusted with rotary control present on top of it with the help of a screw driver. They are used to adjust the sensitivity of the circuit like temperature or light.
Thermistor
It is a temperature sensitive resistor. They are used in temperature sensing, current limiting circuits, over-current protection circuits etc.
Varistor
It is a Voltage Dependent Resistor. It has non-linear current-voltage characteristics. Generally used in circuit protection from voltage surges and excessive transient voltages.
Magneto Resistor
They are also called as Magnetic Dependent Resistors (MDR). The resistance of magneto resistor varies according to the external magnetic field strength. They are used in electronic compass, ferrous material detection, position sensors etc.
LDR
They are also called as Photo Resistors. The resistance of LDR varies with the intensity of the light incident on it. They are generally used in light sensing applications.
Tapped resistor
A wire-wound type fixed resistor with one or more terminals along its length. Generally used in voltage divider applications.
Attenuator
It is a device used to lower the power of a signal. They are made from simple voltage dividers and hence can be classified in the family of the resistors.
Memristor
The resistance of memristor is varied according to the direction of flow of charge. Memristors can be used in signal processing, logic/computation, non-volatile memory etc.
