what is a resistor?

Do you know what is a resistor and how does it work? if you are a beginner maybe you have a question about resistors. So Before discussing more about how does resistor work then you should know first what is a resistor. Resistor is an electronic component that it function it to reduce elektric current flow. Resistors have 2 legs and colorful bracelets in the body

The basic function of resistor is to reduce electric current current

In this time the I’ll discuss about what is a resistor and how does it work in the electronics circuit

Resistor is an electronic component that’s serves as a current holder so that the current can be adjusted as necessary

for example if you open an existing socket off the led light in it surely you will find a resistor

the function of the resistor is as a current buffer if the resistor is released then the led lamp will burn or broken because the led light is not capable if passed a large current

In the resistors there are colored bracelets that express the resistance value of the resistor

what is a resistor and how does it work, how does resistor work

after you know about what is a resistor then the next you also need to know about how does resistor work and how to calculate the resistor value

how does resistor work?

The main function of the resistor is as an electric current holder or as an inhibitor of electric current so that the electric current can be adjusted as needed

how to calculate the resistor value

In the resistor there are color bracelets that show the resistance value of a resistor. Each color bracelet has its own value

The values ​​of these colors are as follows

  • Black = 0
  • Brown = 1
  • Red = 2
  • Orange = 3
  • Yellow = 4
  • Green = 5
  • Blue = 6
  • Purple = 7
  • Gray = 8
  • White = 9
  • Gold = 5%
  • Silver = 10%
  • Colorless = 20%

Before you know about how to calculate the value of the resistor then you must first know the first leg

remember Do not upside down!

The characteristics of the first bracelet are closest to the wire

The characteristics of the last bracelet are gold, silver, or colorless

  • the first bracelet function is to determine the first number
  • the second bracelet function is to determine the second value
  • the third bracelet function is to determine the amount of zero
  • the fourth bracelet (last bracelet) function is to determine the tolerance value of the resistor. Because the value of the resistor may change due to heat

An example of a resistor has the color of the bracelet as follows. What is the value of the resistor?

How to calculate resistor value

  • first bracelet = brown = 1
  • Second bracelet = green = 5
  • Third bracelet = red = 2
  • The fourth bracelet = gold = 5%

So the resistor size above is 1500 + 5% = 1.5k + – 5%
