On 120 volts seven could be used, on 240 v fourteen of them.
NO. Two 60W lamps will use 120W - which is more than 100W !!
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.
To calculate the current drawn by the 100W electric fan motor when plugged into a 240V socket, you can use the formula: Current (A) = Power (W) / Voltage (V). Therefore, Current = 100W / 240V = 0.42 Amperes. So, the motor will draw approximately 0.42A of current.
The 100W bulb emits more light energy per second than the 40W bulb, so it appears brighter due to the higher intensity of light. This increase in brightness is a result of the higher power consumption and light output of the 100W bulb compared to the 40W bulb.
The total energy used in one hour by 10 100W light bulbs is 1 kWh (kilowatt-hour). To calculate this, you multiply the power of each bulb by the number of bulbs and the time they are on. In this case, 100W * 10 bulbs * 1 hour = 1000 watt-hours = 1 kWh.
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
NO. Two 60W lamps will use 120W - which is more than 100W !!
A 25W LED bulb is equivalent in brightness to a 100W traditional incandescent bulb.
Power = voltage times current, and ohm's law state's R = V / I, so the lower wattage light bulb must have the higher resistance.
