  • Surface area of a bulb filament Physics Forums

    Nov 20, 2013 · Keep in mind that what you want to keep constant when changing wattage of the bulb is the temperature of the filament. And since that means energy in = energy out, a 40W bulb is going to have 2/3 of the surface area of the 60W bulb. So you should have no trouble converting the above number to whatever wattage that applies to your computation.Read More
