How To Read Resistor

With that knowledge realize that on a four band resistor the third color will always be blue 106 or less and on a five band resistor the fourth color will always be green 105 or less. If there is no tolerance band then find the side that has a band closest to a lead and make that the first band.

Using A Breadboard And Reading A Resistor Color Code

How To Read Resistors By Its Color Codes Transmission

4 Band Resistor Color Code Calculator And Chart Digikey

The first two bands always denote the first two digits of the resistance value in ohms.

How to read resistor. Decide which band is the first band. Read the color sequence that must be decoded to determine resistance. Basic resistor values range from 01 ohm to 10 megaohms.

Position the resistor with this band on the right side and again read your resistor from left to right. How to read the code. The most commonly seen codes are the three and four digit system and an electronic industries alliance eia system called eia 96.

The value of the resistor is marked on the body using colors. Determine the coded number for the resistive value. To determine the value of a given resistor look for the gold or silver tolerance band and rotate the resistor as in the photo on the left.

Similarly search the color of the second band in the column labeled 2 nd digit. Read the color sequence of the resistor and search the color of the first band in the column labeled 1 st digit of the table given below. Tolerance band on the right hand end of the colors refer to the tolerance chart below for exact values.

Or there are much resistor calculators that you can use. Its for the lazi. Determine the decoded.

Every color is different number and you can remember these numbers or you can just use the table on next step. How to read axial lead resistors steps position the resistor with the gold or silver color band to the right. Look at the first color band and determine its color.

Read the first three stripes to find the capacity ohms. Hold the resistor or diode with the stripes to the left. Determine the tolerance of the resistor.

Decoding the nominal value of a resistor. How to read color codes from resistors. Because of the small size of smd resistors there is often not room for the traditional color band code to be printed on them.

The power flows from the end without the stripe to the end with the stripe. Compare the ends of the resistor. Usually the colored band at one end is closer to that end than is the colored band at the other end.

Therefore new resistor smd codes were developed. The resistor value is read from the left to right. Look for the marking a colored stripe on the diode or resistor that indicates which way the current flows.

Heres how you use the color code to figure out the nominal value of the resistor refer to the figure.
