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
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.
Materials required to study light dependent resistors?
a resistor , two multimeter ,
What is the purpose the light dependent resistor?
This is a Resistors,who's resistance decrease when light energy falls on its surface gradually.
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.
Where are LDRs used?
LDRs (light-dependent resistors, also known as photocells a, can be used for most light-sentsitive applications like "is it light or dark out?", "is there something in front of the sensor that would block light?", "is there something interrupting a laser beam?" (break-beam sensors), or "which of multiple sensors has the most light hitting it?"
What are non ohmic devices give an example?
non ohmic devices are diodes, LED's, Thermistors, LDR(light dependent resistors, cells in series.
How are light dependent and independent reactions related?
The products of light-dependent reactions are used in light-independent reactions.
What are those materials of resistors?
most of the resistors commonly used are carbon resistors
What is the term used for light to put together sugars?
Light dependent reaction.
What product of the light dependent reactions is used by humans?
Oxygen
How much is a resistor for an electronic circuit?
Resistors are tiny devices on circuit boards. Prices should range but should not be expensive but dependent on the materials used and the nature of conductivity.
