What is LDR ? | How LDR works ?

 

ANSWER THIS QUESTION:-

From which material LDR is made ?

  

HELLO FRIENDS.

 

Light Dependent Resistance


A Photo resistor or Light Dependent Resistor (LDR) is a resistor whose resistance decreases with increasing incident light intensity. When Light falls on it, Its resistance becomes low and in dark its resistance is high.


It come in range for ex:- 5k, 10k, etc. & also watts.

 

SYMBOLS:-

 

USES:-

Projects like:-

Automatic street light.

Morning alarm.

And many more.

  What is RGB LED? | how it works?   HELLO FRIENDS.   RGB LED   An RGB LED, as name suggests is a special LED which is capable of producing all colors by mixing Red, Green and Blue colors . In simple words It consists of 3 LEDs (Red, Green, Blue) together in a package and by variation of these 3 colors more colors can be formed.   An RGB LED is having 4 pins, one of which is a common anode and other 3 pins are for Red, Green and Blue respectively. Or common cathode and other 3 pins are Red, Green, Blue.   So, to distinguish between common cathode and common anode RGB LEDs: Use a multimeter in continuity mode. If the LED lights up with the red tip on the longest lead and the black on one of the other leads – you have a common anode RGB LED If the LED lights up with the black tip on the longest lead and the red tip on one of the other leads – you have a common cathode RGB LED.   By manufactur...

  What is reed switch? | how reed switch works? HELLO FRIENDS.   Reed Switch   The reed switch is an electrical switch operated by an applied magnetic field .   CONSTRUCTION:- It consists of a pair of ferromagnetic contacts on iron metal reeds in a sealed glass envelope. When a magnet comes near to this switch, it magnetize the iron reeds and come together to make a contact. This temporary contact works as a switch. The moment magnet moves away, the switch turns Off and contacts are separated.   SYMBOL   Hey it’s   TECH BECK.
