On 120 volts seven could be used, on 240 v fourteen of them.
600w - the thicker filament has a lower resistance, which leads to a higher current and thus higher wattage
answer is 2 lamps...For 200w/220vp1=v*i1200=220*i1we get i1=10/11v=i1*r1220=(10/11)*r1r1=242 ohms --------------1For 100w/220vp2=v*i2100=220*i2we get i2=5/11v=i2*r2200=(5/11)*r2r2=484 ohms----------------2As n no of 200w/220v lamp is connected in series should consume the same power as that of single 100w/220v lamp ....(v^2/n*r1)=(v^2/n*r2)-----------------3substituting 1 and 2 in 3 ,we get..n=2hope am right...if not correct me...ANSWERUnfortunately, you are wrong.As the resistance of each lamp filament is temperature dependent (a hot lamp has up to 18 times its cold resistance!) , there is no way of determining the resistance of each lamp when subjected to a voltage other than its rated voltage because we don't know the operating temperature at the reduced voltage. So there's no way of calculating the resulting power of each lamp when connected in series and subject to half its rated voltage. So this question cannot be answered.
If the fixture was the exact same, and one held a single bulb and one held a double bulb then NO. The light given off bulbs is marked as wattage when you look at the package. So a 100w bulb has less light than two 75w bulbs together, because the two equal 150w.
Based on 7 cents a kilowatt hour, your cost would be seven one hundredth of a cent.
There are 60W, 75W, 100W, and 150W bulbs. No standard 110W.
The 100w light bulbs were no longer being manufactured by 1st September 2009. Although some people still have these types of lights around their homes, the manufacturing companies has stop producing them.

The typical wattage of a tanning bed bulb is 100W, but you need to check the size of the bed to make sure.
Assume the rating of 100W refers to operation on a supply of 117 volts.Power = (voltage) x (current)Current = (power) / (voltage) = 100/117 = 0.855 ampere (rounded)Power = (voltage)2 / (resistance)Resistance = (voltage)2 / (power) = (117)2 / 100 = 136.89 ohms
Power = voltage times current, and ohm's law state's R = V / I, so the lower wattage light bulb must have the higher resistance.
600w - the thicker filament has a lower resistance, which leads to a higher current and thus higher wattage
