Resistance: ohm

Error ±: ohm

Usage example

Pronunciation

Example: 4-ring resistance in order: red, yellow, red, gold, read as 2400Ω = 2.4K, error is ± 5%

Example: 4-ring resistance in order: orange, white, red, silver, read as 3900Ω = 3.9K, error is ±10%

Example: 4-ring resistance In order: yellow purple orange silver read as 47000Ω = 47K error is ± 10%

Example: 4-ring resistance In order: orange orange gold and silver, orange orange is 33 multiplied by 10-1=3.9Ω, error is ±10%

Example: The 4-ring resistance is in order: yellow-violet-silver-silver, where yellow-yellow is 47 multiplied by 10-2=0.47Ω, and the error is ±10%.

Note

From the above, it is known that reading the third color ring is gold or silver, because it is a negative multiplication, and the resistance value is generally 0.1-9.9 Ω.

Regarding the error rate: the number of errors in the software must be multiplied by 100. If the calculated error is 0.02, multiply by 100=2%.
