photo resistors, or light dependent resistors, are devices with variable resistance, that cahnges depending on how much light is hitting the device
Its slows down energy when it passes thought the light depntent resistor.
This is a Resistors,who's resistance decrease when light energy falls on its surface gradually.
security lights use resistors as the light out side falls the security light turns on and as it gets lighterbout side the light dimms and turns off, in bmw's the resistors are used to detect when the lights should come on as light gets brighter the car lights turn off.
Light-dependent resistors (LDRs) are typically made using semiconductor materials such as cadmium sulfide (CdS) or lead sulfide (PbS). These materials exhibit changes in resistance based on the intensity of light they are exposed to, making them ideal for light sensing applications. LDRs are commonly used in electronic devices to control the amount of light reaching a sensor or to trigger certain actions based on light levels.
non ohmic devices are diodes, LED's, Thermistors, LDR(light dependent resistors, cells in series.
Cadmium sulphide (CdS) has been used since before bulk silicon was available. Besides Silicon is used as a semiconductor for making electronic transistors. Resistors have to be put on it. Cadmium Sulfide is cheap and works fine.
The materials that enter the chloroplast for use in the light-dependent reactions include water molecules and light energy. Water is split into oxygen, protons, and electrons, while light energy is absorbed by chlorophyll to initiate the photosynthetic process.
For the light-dependent reactions of photosynthesis, materials needed include sunlight, water, chlorophyll, and other pigments, as well as enzymes and other proteins involved in the electron transport chain and ATP synthase. These reactions take place in the thylakoid membranes of chloroplasts.
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
Light-dependent resistors (LDRs) are commonly used in devices such as streetlights, cameras, and mobile phones to detect light levels and trigger appropriate responses, such as turning on/off the light or adjusting the screen brightness.
