• Oct 12, 2025 1 4w Resistor , and Gold (5% tolerance) represents a 100 Ω resistor with a ±5% tolerance (meaning its actual value could be between 95 Ω and 105 Ω). If the resistor has five bands, the additional band represents a significant figure and increases the precision. Ohm's Law: Calculating Power Dissipation Ohm& By Juan Walter
