What is resistor?

 

HELLO FRIENDS.

 

Resistor is a two terminal passive component which resists the current.

For eg:-  A river is flowing on his path and a stone is placed in the way of river. Stone works as resistor.

 

CONSTRUCTION:-

The terminal of resistor is made of aluminium, and the semiconductor is made of carbon or metal or metal oxide.

 

CALCULATION:-

A resistor is calculated in two main ways.

·       Multimeter

·       Color code scheme

 

For Color code chart click here:-

·       Mltimeter method is simple, just attach to probe on two side and set multimeter on resistance Ω.

·        In color code is also quite simple, just see the chart or watch the video.

Each color represent a number.

For eg:- black=0, brown=1, red=2, orange=3, etc.

 

A TIP:- to remember the color code just resite (bad beer rots our young guts but vodka goes well, get some now). It means (black, brown, red, orange, yellow, green, blue, violet, grey, white, gold, silver, no color).

 

USES:-

·       Current limiting

·       Voltage divider

·       Signaling

·       Sensor

  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.
