Can you run a 1500w power tool on a 3kvA 240W to 110W step down transformer?

I think you mean a 240 V to 110 V (volts, not watts) transformer! Providing your power tool is rated at 110 V, the answer is yes, because its power rating of 1500 W is well within the capacity of a 3-kV.A transformer.

A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the effective resistance of the three esistors?
The effective resistance of three resistors, 120 ohm, 60 ohm, and 40 ohm, in parallel is 20 ohms.RP = 1 / sum (1 / RN)RP = 1 / (1 / 120 + 1 / 60 + 1 / 40)RP = 20The voltage applied, 120V, does not change the outcome. The power, however, of the three resistors is 120W, 240W, and 360W respectively. This is a lot of power, so please do not attempt to do it for real.
A television uses a current of 1.5 A at 120 V The television is used 2 hours Calculate the power used in KW and the energy used in kWh?
40A*120V*5Hr = 24kW*Hr (Kilowatt-Hours)CommentNo television would ever draw a current of 40 A!!!! Think about it, for a 120-V supply, that would make it have a power rating of 4800 W!!!!!! You would be able to use it for central heating!!!!
1 kw equal to how many amps?
A kilowatt-hour is a unit of energy. The amp is a unit of electric current. Current and Energy are fundamentally different things, and cannot be compared directly. To determine the energy dissipated by a current one would need to know the time for which it flowed, and the potential difference through which the associated charge was moved. the product of current by potential difference by time would give the energy. If one assumes the current flows for one second through a potential difference of one volt then the energy in joules would be numerically equal to the current in amps. One kilowatt-hour (kWh) is 3,600,000 joules, so to get the answer in kWh divide the energy, expressed in units of joules, by 3600000 .Or you can use an easier method, its called Ohms law however one element is missing, the voltage is required. according to Ohms law Watts= Volts x Amps so if the circuit is 120 Volts the answer would be found by 1000 watts (1kW) divided by 120 volts and you get 8.333 Amps forget the Joules unless your a master electrician and fully understand it, even though we use Ohms law because it is sooooo much easier. if you Google the Ohms law chart remember Power is represented by a P Current is Amps and will be represented by C or R, Resistance is Ohms and is represented by a R and Voltage is represented by E
Can your 240w Australian fridge work on 110 power supply US?
I think the numbers should both be voltages, if so, absolutely not.

What is the age of a Winchester shotgun model 240w?
I bought one new from Montgomery Wards about 25 years ago
What is the age and value of a 20 gauge Winchester Western Field Model 240W shotgun?
I have a Winchester Model 240W Westernfield "12 ga." (not 20ga.) shotgun. It was a knockoff of the Winchester model 1400, made for Montgomery Wards. I've seen them sell anywhere between $200 and $250 depending on condition.
How are mackie pro audio speakers rated?
Depends on the speakers. Usually something like 60W RMS, 240W Peak.
Do you have any history on N925482 240w 20gauge shotgun?
Without a maker's name, can't be answered. Even then, ther may be no info.

How long will a 600VA inverter provides backup power with 80 and 100 Amps Battery?
based on the load,your battery back up may determined.for 600va inverter u can provide a maximum load of 460w(app.)for fan its 80w and tubelight it's 40w.if your using 100ah battery,your backup for running the 2 fans and 2 light have load upto 240w is 5hours(app.).duration may differs based on the efficiency of the battery

Iv got 120 36 watt 12 volt halegen spot lights if you changed them to led how much could you save?
120 x 36 = 4320w which is 4.32kw. in England to run these lights for 1 hour would cost you approx 45 pence. 120 x 2 = 240w which is 0.25w. to run 120 led spot lights for 1 hour would cost you approx 2.5 pence. so the saving is quite vast. dean burnley
Can you add 600 watt power supply to a computer that currently runs a 350 watt power supply?
Yes you should be fine. As long as it fits in the computer, you're fine. Replace the old with the new one but keep the old one in case the new one doesn't work! 300 watts is fine for replacing something smaller. You should run only one power supply at a time. What this means is that you should replace the 185 Watt supply with the 300. Having 2 separate power supplies creates the possibility of having slightly different values for ground, +5V, and +12V DC. This can cause problems with all of your computer components. Don't use both, replace the old one with the better one. <- There are some motherboards that REQUIRE two power supplies, but you probably don't have one. They're server mb's, and the reason you use dual supplies is, if one supply dies the computer uses the live one and notifies the system operator "one supply just cooked, get me a new one pls." This eliminates a point of failure. If you've got one of these mb's, both supplies have to be the same: two 300w, two 750w, whatever. Really, though, with the amount of juice some of these new video cards pull, I wouldn't even consider installing a 300w power supply in anything except a server, a lot of which are "headless"--they don't have video outs, you control them over your network. Go with at least a 500w supply, and if you might have the need for a dual-head system--two monitors are GREAT, don't let anyone tell you different--go with a 1200w supply.
