Fast identification method for color ring resistance 3

For a 4-color ring resistor, the calculation method for its resistance value is:

Resistance value=(1st color ring value * 10+2nd color ring value) * multiplier represented by the 3rd color ring

For a 5-color ring resistor, the calculation method for its resistance value is:

Resistance value=(1st color ring value * 100+2nd color ring value * 10+3rd color ring value) * multiplier represented by the 4th color ring diode

Example 1: The color identification of a 4-color ring resistor is as follows:

The nominal resistance of this resistor is 26 * 107=260000000 Ω=260M Ω, with an error range of ± 5%

Example 2: The color identification of a 5-color ring resistor is as follows:diodeThe resistance of the resistor is 508 * 1000=508000 Ω=508K Ω, with an error range of ± 5%

For a 4-ring resistor, the first 2 rings are directly replaced with numbers, and the third ring represents a power multiplied by 10. For example, if the colors of the first, second, and third rings are brown (1), purple (7), and red (2), respectively, then the resistance represented is 17 × 10 ^ 2, which means a resistance value of 1.7K.

For a 5-ring resistor, the 4th ring represents a number multiplied by a power of 10, and the numbers represented by the first 3 rings are multiplied by the nth power of 10 (where n is the number represented by the 4th ring).diode
