Standard resistors are extremely high accuracy resistors used as reference to calibrate or check the accuracy of other resistors in industry or establishments, on the production lines or equipment. These are also used to check accuracy of resistance meters all over by most manufacturers.
Considering this, what three values are most resistors rated in?
Resistors are rated by the value of their resistance and the electrical power given in watts, (W) that they can safely dissipate based mainly upon their size.
Furthermore, why do resistors have different values?
So to overcome this, small resistors use coloured painted bands to indicate both their resistive value and their tolerance with the physical size of the resistor indicating its wattage rating. These coloured painted bands produce a system of identification generally known as a Resistors Colour Code.
What are the most common resistor values?
The most common series are:
- E6 20%
- E12 10%
- E24 5% (also available with 1%)
- E48 2%
- E96 1%
- E192 0.5% (also used for resistors with 0.25% and 0.1%).
What are the 4 types of resistors?
The types of resistors include:
- Carbon Composition Resistor.
- Wire Wound Resistor.
- Metal Film Resistor.
- Carbon Film Resistor.
- Variable Resistor.
- Light Dependent Resistor.
