Resistor color codes convey which two attributes?

Explanation:
Resistor color codes convey resistance value and tolerance. The colored bands encode the digits of the resistance and a multiplier to set the scale, with a final band indicating how precise that value is (the tolerance, such as ±5% or ±1%). This coding lets you read a resistor’s value quickly without printing numbers on the body. Voltage rating and power rating aren’t determined by this basic color code, and current rating isn’t typically conveyed by these bands. Some high-precision resistors may add an extra band for temperature coefficient, but the standard two attributes communicated by the color bands are the resistance and its tolerance.
