Diodes, LEDs, Thermistors and LDRs _ GCSE Physics

The video tutorial covers the basics of diodes, including their resistance properties and voltage measurement. It explains the function and benefits of light-emitting diodes (LEDs), highlighting their energy efficiency and longevity compared to filament bulbs. The tutorial also discusses thermistors, which are used as temperature sensors in devices like fire alarms, and how their resistance changes with temperature. Finally, it explains light-dependent resistors (LDRs) and their role in adjusting to light levels, with resistance decreasing as light intensity increases.
