13.5. Resistor Circuits http://www.ck12.org

We now know that the 20Ωis the brightest, 10Ωis second and then the 90Ωand last the 10Ω(-these last two have

same current flowing through them, so 90Ωis brighter due to its higher resistance).

∗Note: Adding up these two plus the 9.5W from the 20Ωresistor gives us 13.8W, which is the total power

previously calculated, so we have confidence everything is good.
