How to read the resistance color code

电阻颜色代码

The color code of the resistor is the standard method of recognizing the wire of the resistor in the circuit.Also known as resistance or Ohm meter -resistant reading method.This page explains how to identify the resistor with color code, and introduce you to different resistor types, as well as their physical characteristics and applications.

What is a resistor?

The resistor is a passive element that hinders current flow.People use resistors to control the current in the electronic circuit to avoid device burning.When you turn on the light of the room, the filament in the fluorescent bulbs is connected to the switch or power supply.Once the filament is connected to the switch, nothing happens, because the switch does not "open" and it has nothing to connect.If you power the bulb, the filament will be connected to the terminal of the switch, and the room will become brighter.A resistance between the switch and the filament to reduce the current.If you want to provide a higher voltage for the bulb, you need to buy different switches or find a way to reduce the current.

Color code based on resistor

The resistor is identified with its color code.Color code is a standardized method for identifying the resistor.Electronic devices use color code. Humans cannot see the color, but they can identify the resistor through it.Each color code represents a section of resistance.The greater the color change, the higher the resistance.Common color codes are: with the color code, you can use a digital multimeter to determine the resistance value of the resistance.

The graphic representation of the resistor color code

The color code of the resistor is represented by a graphic.The figure does not use a form, but shows how the resistor's resistance changes with voltage.The resistance is connected or connected in parallel.Therefore, the resistance value of the resistor changes with the current or voltage.The figure shows the resistor of the resistor at multiple points.This is like looking for a route diagram in the circuit.X axis represents voltage and Y axis represents resistance.From the figure, you can see where the resistor is connected to the circuit.

Why is color code important?

People use color code to identify the wire because it provides the same information.The color code of the resistor provides information about the resistor resistance.The color code of the resistor is not only used to identify, but also to calculate the resistance value of the resistor.The computer uses resistance color code to control the power supply of the device.The computer sends a control signal to the power supply to tell it how much voltage and current to generate.

Important note:

The color code of the resistor is a guide instead of force.Different manufacturers use different color code for resistors.When buying a resistance, be sure to look at the packaging or data table of the resistance.You must find the value of the resistor and other useful information there.All resistors have a maximum current limit.The load capacity of the resistor is indicated on the data table of the resistor.The value of the resistor cannot exceed its maximum load capacity.

in conclusion

The resistor is used to reduce the current or voltage in the circuit.The color code of the resistor tells you the value of the resistor, the value of the circuit, and the connection position of the resistor.The resistance color code is important in the electronic circuit.The resistor is very important in the electronic circuit.But the resistor is a very simple component that can use the resistor color code to identify it.All you need to do is to remember the color code of the resistance.Now you know how to use the color code to identify the resistor and tell you different resistor types, as well as their physical characteristics and applications.
