Practical Applications of Thermistors and Light Dependent Resistors

This video tutorial covers the practical applications of thermistors and light dependent resistors (LDRs). It begins with a recap of resistors, explaining how they restrict current and convert electrical energy to thermal energy. The video then explores thermistors, which change resistance with temperature, and their applications in devices like thermostats, fire alarms, and fridges. Finally, it discusses LDRs, which alter resistance based on light intensity, and their use in street lights and cameras.

What happens to the current flowing through a thermistor as the temperature changes?

Explain how light dependent resistors can affect the shutter speed of a camera.
