How many 100w light bulbs connceted 6a circuit?

On 120 volts seven could be used, on 240 v fourteen of them.


There are three bulbs of 600W 100W and 200W which bulb has thickest filament?

600w - the thicker filament has a lower resistance, which leads to a higher current and thus higher wattage


What power is used by two 100 watts bulbs with 220 volts connecting in series?

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.


Will four 50 watt halogen bulbs give as much light as eight 40-watt incandescent bulbs?

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.


Cost to power a 100w light for one hour?

Based on 7 cents a kilowatt hour, your cost would be seven one hundredth of a cent.

What is the typical wattage of tanning bed bulbs?

The typical wattage of a tanning bed bulb is 100W, but you need to check the size of the bed to make sure.


What is the current being drawn by a 100W light bulb and what is the resistance of a 100W light bulb?

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


If you have two light bulbs running on 120V circuit one is 50W the other 100W which has high resistence?

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
