I have ten 12 volt 10 watt lights what transformer do you need?
To power ten 12 volt 10 watt lights, you would need a transformer with a total output of at least 120 volts and 100 watts.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
How many kw in five hours does 10 20 watt 12 volt lights use?
If you have ten 20-watt lights running they take a power of 200 watts, continuously. If run for 5 hours they take 200x5 watt-hours of energy, which is 1000 watt-hours or 1 kilowatt-hour. That would register as 1 unit on a domestic electricity meter. This does not depend on the voltage of the lamps.
How do you determine watts per square foot and total volt amp?
For lighting using CFL bulbs you can use 10 square feet per watt. The volt-amps is the volts times the amps, or the watts divided by the power factor. Most CFL bulbs are marked with the voltage and the current.
How many watt-seconds does a 60 watt bulb use in 10 hours?
You multiply the watts by the seconds. 10 hours is 36,000 seconds, so the watt seconds is 60 x 36,000 Answer 2,160,000 watt-seconds You can also say the bulb uses 60 x 10 or 600 watt-hours.

How many watts of lighting is required in a 15' x 10' room?
'Lighting', or the amount of light is not measured in watts. A 'watt' is a unit of power, measurement of current drawn. Most 100 watt/110 volt lamps initially produce 1690 lumens (a 'lumen' is the measure of the total "amount" of visible light emitted by a source). A 15 foot by 10 foot room is not very big, and one or two 100 watt incandescent lamps on a ceiling light fixture on a 120 volt service can light it adequately. I mention "110 volt" as in parts of the world with 220 mains these numbers change. As the voltage is doubled, the watts required would halve for the same amount of light. In other words, all other things being equal, a 50 watt 220 volt lamp should use the same amount of power, producing the same amount of light as a 100 watt 110 volt lamp.
How do you distinguish between an 80-watt and 120 watt motor for a 1986 Toyota Tercel?
On a 12 volt system the 80 watts draws 6.7 amp and the 120 watts draws 10 amps.

How can you minimize the wastage of electricity?
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.
How do you find kva?
k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA

How do you reduce 14 volt DC to 10 volt DC?
Use a properly rated potentiometer.

Can you use a 10 volt power supply for a 9 volt keyboard?
Using a 10 volt power supply for a 9 volt keyboard is not a good idea. The higher voltage will cause damage to the keyboard, burning it out and making it useless.
Can I use a 10 amp 125 volt power cord on my computer's 6 amp 125 volt input?
Sure
