Dependent Resistors (LDR, NTC, PTC and VDR)

Dependent resistors, also known as variable resistors, are resistors whose resistance values vary based on certain external factors such as voltage, current, temperature, or light intensity. These resistors change their resistance in response to changes in specific environmental or electrical conditions.

There are several types of dependent resistors: Light-dependent resistor (LDR), Thermistor (NTC, PTC) and Voltage-dependent resistor (VDR)
