In addition, the calculated unknown resistances (Rx) were proven to be correct by comparing them to the value obtained by using the Resistor Color Code Chart. The calculated resistance for the first unknown resistor was 100 ohm and according to the Resistor Color Code Chard it has a resistance of 100 ohm. The calculated resistance for the second unknown resistor was 224 ohm and according o the Resistor Color Code Chard it has a resistance of 220 ohm. The calculated resistance for the third unknown resistor was 479 ohm and according o the Resistor Color Code Chart it has a resistance of 470 ohm. Since the values obtained for each unknown resistor (Rx) were similar to their respective Resistor Color Code Chart values, it can be concluded the calculated unknown resistor values were indeed proven to be correct.
