5 color band resistor value calculator

Reading method:

Example: 5-ring resistor is: red, yellow, red, black, gold, read as 242Ω

Error is ±0.5%
Example: 5-ring resistor is: orange, white, yellow, red, silver, read as 39400Ω=39.4K

Error is ±10%
Example: 5-ring resistor is: orange, orange, red, gold, red, orange, orange, red is 332Ω, multiplied by 0.1=33.2Ω

Error is ±2%

From the above, we know that we must pay attention to reading the fourth color ring as gold or silver, because it is a negative number of multiplication.

About the error rate: The error rate of this software must be multiplied by 100. If the calculated error value shows 0.02, multiplied by 100=2%
