Which color indicates a tolerance of 10% in resistor tolerance codes?

Explanation:
Tolerance shows how much the actual resistance can vary from its stated value, and the last color band on a resistor marks this tolerance. Silver corresponds to a 10% tolerance, so a resistor with a silver tolerance band may vary by ±10% from its nominal value. Gold would be ±5%, no color indicates ±20%, and red indicates ±2% (a tighter tolerance). Therefore, silver is the color that signals 10% tolerance.
