GCSE Physics - Components #19

The video tutorial covers various components of electrical circuits, including power sources like cells and batteries, and control elements such as switches. It explains the function of filament lamps, fuses, and diodes, including LEDs. The tutorial also introduces measuring instruments like ammeters and voltmeters, and discusses different types of resistors, including fixed, variable, light-dependent resistors (LDRs), and thermistors. LDRs are highlighted for their use in light-sensitive applications, while thermistors are noted for their temperature-dependent resistance, useful in devices like car engines and thermostats.

What is the role of light-dependent resistors (LDRs) in circuits?

How do thermistors function as temperature receptors?
