240
The formula for amps is I = W/E. Amps = 40/240 = .17 primary amperage. For the secondary amperage I = W/E. Amps = 40/24 = 1.7 amps.
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
If your generator is rated at 1000 watts continuous......and you are using 120V.....available amps are 1000/120 =8.3 .
10A
On a 120 v supply 320 watts is 320/120 amps, or 2.667 amps. On a 240 v supply the current is 320/240 amps, or 1.333 amps.
3000 divided by 240 approx 13 amps?
1000 watts at 9.5AMPS in 120 volt = 4.7 AMPS in 240 volt ..........Divide that by 2 according to the choice of voltage... 500 watts (120V) + 4.7Amp
On a 120 volt supply, up to 360 watts. On a 240 volt supply, up to 720 watts.
Your electric bill is computed in kilowatt-hours. This is a measure of power over a period of time, which is a combination of volts and amps. Amperage at 240v would be half that of 120v, but obviously the voltage is double. So the net watts are the same. As a result, your net kilowatt-hours will be the same whether you use 120v or 240v.
You can't. The 120 volt GFCI is probably just a 2-wire (hot, neutral and ground) You would have to run a new 3-wire (2 hots, neutral and ground). The two hots are how you get the 240 volts (120+120=240). Also you must make sure the wire is gauged properly. #10 wire for 30 amps, #12 wire for 20 amps, etc.

calculation for Watts is = volts X amps P=IE P= Power(WATTS) I = Current(AMPS) and E = Voltage(VOLTS). So: I = P/E and E = P/I therefore: 1 watt = 1 ampere x 1 volt If you havea 240 volt lamp that is drawing .5 amp then it is using 120 Watts
That depends on the voltage, but the residential standard is 240 volt. At that voltage you sit at around 15 amps, however it MUST be on a 20 amp circuit for national (US) or Canadian electrical code, as you can only load your circuit to 80% of it's capacity.
It depends on the voltage.Amps times volts equal watts
Both work just as well. The only difference is what the supply voltage is at hand. Heaters are rated in watts. Your electric bill is rated in watts consumed per hour. Watts = Amps x Volts. An example, 500 watt heater at 120 volts will equal 4.16 amps. The same heater at 240 volts will equal 2.08 amps. As you can see if the voltage goes up the current goes down but the wattage total is always the same. That is the reason that you are billed on wattage, and not on what the service voltage or the current draw of the service is.
On a 1kva you have 1000 watts capacity. To fine the current the formula is I = W/E. The secondary side of the transformer has the capacity of 1000/120 = 8.3 amps. In your question you do not put the amps across the secondary you draw amps from it. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. <<>> voltage times amps equals wattage
