Yellow and green represent 4 and 5, respectively. Example and problems for 6-band resistor.Example and problems for 5-band resistor.Example and problems for 4-band resistor.
Resistors whose value can vary according to the temperature or voltage applied to these however, these resistors do not follow Ohm’s law. Variable resistors are of the following types:ī. We can find their applications in radio receiving stations for controlling volume and tone. The value of variable resistors can be varied with the help of a dial, knob, or screw. Thin-film resistors are of the following types: Thick film resistors are of the following types: Fixed resistors are of the following types: Linear Resistors are of two types, viz: fixed resistors and variable resistors, let’s discuss their types:Ī fixed resistor has a fixed specific value that means its value cannot change whatever the conditions it is being subjected to. Resistors whose value varies with the change in the applied temperature and voltage are called linear resistors. There are two types of resistors these are as follows:Ī. Terminate the transmission lines and many more places. In electronic circuits, resistors are used to reduce the flow of current through the circuit, they are also used to perform the following operations: We define a resistor as a passive two-terminal electrical component that is used as an electrical resistance viz: an element of the circuit. Now, to calculate the minimum and maximum resistance values, we need to multiply the resistance value by the tolerance percentage to obtain the following values: The fourth band, i.e., gold indicates the tolerance of ±5% (as given in table a). So, the minimum value is 750 kΩ or 75 10⁴ Ω. So the multiplication will be: 75 x 10000 = 750000 Ω Now, we will multiply that number by the multiplier indicated with the third band, i.e., yellow and it has the value of 10⁴ or 10000.
The first two colors in the four-band resistor, viz: violet and green indicate the significant digits (i.e., 75) which are according to the above table (a). Let's suppose that we take a four-band resistor with the following band colors: Now, let’s discuss the resistor color coding formula:įor calculating the resistance colour code calculator, we need to group the values of the significant digits bands it means we will take the values of the first two or three bands from the left, depending on the total number of bands, then we will multiply that value by the multiplier to get the resistance value of the resistor.
