What else can I help you with?
What are photo resistors?
photo resistors, or light dependent resistors, are devices with variable resistance, that cahnges depending on how much light is hitting the device
Where are light dependent resistors used for?
Its slows down energy when it passes thought the light depntent resistor.
What is the purpose the light dependent resistor?
This is a Resistors,who's resistance decrease when light energy falls on its surface gradually.
What products use Light Dependent Resistors?
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.
What are the materials used in the manufacture of ldr?
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.
What are non ohmic devices give an example?
non ohmic devices are diodes, LED's, Thermistors, LDR(light dependent resistors, cells in series.
Why do you use cadmium sulphate in light dependent resistors instead of silicon?
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.
What materials come into the chloroplast that used in the light dependent reactions?
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.
What materials are needed for light dependent reaction?
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.
What are the stage in the process of photosynthesis?
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.
What devices use a LDR?
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.
What are two stages in the process of of photosynthesis?
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.
