These make up the third or fourth band–depending on if it is a four or five band resistor–and are the multiplier. These make up the first two or three bands–depending on if it is a four or five band resistor–and therefore make up the value of digits.
#100 ohms resistor color code code
Values for Different Colors on Resistor Code For five band resistors, the first three bands are the value digits, the fourth is the multiplier and the fifth is the tolerance. For four band resistors, the first two bands are the value digits, the third band is the multiplier and the fourth is the tolerance. For resistors with a tolerance anywhere from 1% to 2%, there will be five bands. For resistors with a tolerance anywhere from 5% to 10%, there will be four bands. Reading Resistor CodeĬount the number of color bands on the resistor. In other words, by using different colors, an average user can determine exactly what the Ohms are for the resistor. Therefore, a system was developed to use colors to determine the resistor code. However, unless the size of the resistor is large, the code is rarely written on it because it would require very tiny markings. Resistors can come in different sizes and shapes allowing for different voltages to go through it. Tolerance is the product of the value of the resistor and the tolerance band value. To remember the color code sequence of color code given above by the sentence given below,ī B ROY of Great Britain has a Very Good Wife wearing Gold and Silver necklace.
#100 ohms resistor color code how to
How to remember the sequence of the color code : So the resistance of the given resistor Red blue violet gold will be 26×107 ±5% Ω It is the resistor color code calculator Reading of a resistor color code :Īccording to the given diagram of the resistorįor red and blue we will put the values of the digit, for violet we will write multiplier and for gold we will write tolerance.įor violet digit is 7 so the multiplier is 107
Black colour code is 0, brown colour code is 1, red colour code is 2, orange colour code is 3, yellow colour code is 4, green colour code is 5 and so on. The gold colour code is the multiplier to the resistance value. There are 10 signal digits from 0 to 9 which corresponds to 10 colors.Īs shown in the table, different colours represent different values in the resistor colour code. Resistance colour code chart or resistor color code calculator are used to calculate the resistance and tolerance values of resistors. From the colors of the resistor we can calculate the resistance of the resistor. From the above diagram we can see that the yellow color is apart from the two red and brown color. The fourth color is drawn apart from the three consecutive colors. Two conducting metal wires are taken out from either side of the shell along its axis through which the resistor is connected to the external circuit. The value of resistance can be determined by calculating the color codes drawn on the resistance. The carbon resistors are cheaper than metal resistors.Ī cylindrical shell of bad conductor is used to made carbon resistor. Carbon is very effective as an element of high resistance. The allotropes of carbon are thousand times greater than metals. These resistors are known as carbon resistor.
Nowadays, high resistances graphite and gas carbon are used widely. Usually in electronics goods resistances are less than 1000 ohm. These types of resistances are generally made of copper or any other conducting metal or alloys. In the electrical experiments resistances starting from about 0.1 ohm to 1000 ohm are widely used.
