Want this question answered?
Incandescent bulbs use 75-100 watts. Fluorescent bulbs use around 10 watts. LED bulbs usually use 1 watt.
we can use 12 no's
Modern table lamps use all sorts of different light bulbs. Most commonly one can find standard 20 watt to 250 watt light bulbs in modern table lamps.
A single bulb is better if you can get it, it's simpler to use, but 23 watt bulbs are easier to find. Five 23 w bulbs totals 115 watts so they would be a little brighter.
two 40 watt bulbs in 24 hours use: 2*40*24 watt hours in practical uses, kilowatt hours are used divide by 1000 to change the units thus two 40 watt bulbs in 24 hours use 1.92 kilowatt hours
Depend on watt and voltage use of light bulbs. You can use this ohm's law formular to calculate the current draw on light bulbs. I (current in amp) = P (watt)/ E (voltage) If 25W light bulb use in 115V AC (resident home) then current draw will be: 25/115 = 0.22A or 22 miliamperes. Hope this help.
This question does is not answerable. A watt is a volt times an amp. With out knowing how many amps the bulbs use there is no answer.
Define "wasting electricity"? A 100 watt light bulb burning in the attic 24/7 is waste, if you ask me. If you mean "reduce electrical consumption"....yeah, lots of ways. Use 60 watt bulbs instead of 100 watt bulbs. Or better yet - use a flashlight instead of bulbs. Use a gas hot water heater instead of electric. Raise your AC thermostat 10 degrees. Use LED bulbs. Get rid of all your televisions. etc... etc..... You didn't say "...and be practical about it.
If both bulbs fit into the same socket I would presume this to be fine.
yes, it can be used - single phase voltage of 230v. 50HZ is important
A zero-watt bulb is a lightbulb that uses little power. Contrary to the name, these bulbs are not in fact zero watts. The reason they are colloquially called "zero watt" bulbs is because when they were first made, they only had a power consumption rate of 15W but testing equipment at the time was unable to detect such low wattage causing people to think they didn't use any power.Todays "zero watt" bulbs are as little as 10W.Read more: What_is_actually_a_zero_watt_bulb
