resistor color code formula

R multiplier x. In this section we have explained the rules of resistor color code for 3 4 5 and 6 band carbon.

Resistors Color Code With Diagram

The resistor colour code print is as shown below.

. 2 nd Color Band Second Number of value of. The values of color bands will be like this. The formula to find the resistance of 5 band system is.

Resistance 1st Digit x 10 2nd Digit x Multiplier. 1 st Color Band First Number of Value of Resistor. 5 Band Resistor Color Code.

Green 5 Brown 1 Violet 7 Black 100 Gold 5. In short If there are three color bands marked on a resistor it means. The first two digits of the band show the value of.

The Red band of the resistance value is 2 and the brown band of the resistance value is 1 from the table. Instructions Diagram Number of Bands 4 Band 5. Using the formula and chart above.

I VR We can find power using PVI V is the voltage across the resistor in Volts I is in current flowing through the resistor in Amperes R is the resistance of the Resistor in Ohms Ω By. Green brown violet black gold and orange. The 5 band resistor color code has 3 digits 1 multiplier and 1 tolerance at the end.

Select the number of bands then their colors to determine the value and tolerance of the resistors or view all resistors Digi-Key has to offer. Calculating Resistor Color Codes 3 Band Resistor Color Code. Body End Stripe Body 1 st digit End 2 nd digit Stripe Multiplier.

Then the color code of 1k ohm resistor with. For a 3-band resistor color codes the first two bands always denote the first two digits of the resistance. If the temperature coefficient of the 1k ohm resistor is 05 then the color of sixth band will be green which is coded by the digit 5.

Body End Dot Body 1 st digit End 2 nd digit Dot Multiplier. For calculating the resistance colour code calculator we need to group the values of the significant digits bands. This resistor read from left to right has the colored bands of RED VIOLET YELLOW SILVER.

Therefore the color code for a resistor contains numbers and letters. It means we will take the values of the first two or three bands from. If the colors on a 6 band resistor is in this order.
