Color ring resistance identification method

The five-ring resistance is a precision resistor. The first three rings are numerical values. The last ring is also an error color ring. It is usually three colors of gold, silver and brown. The error of gold is 5%, the error of silver is 10%, and the error of brown is 1%, the colorless error is 20%, and occasionally there is a green color error, the green error is 0.5%. Precision resistors are commonly used in military, aerospace and other aspects.
