To calculate the cost per hour, we first need to convert the power consumption from amps to kilowatts. We can do this by multiplying the current (amps) by the voltage (110 volts). Next, we convert kilowatts to kilowatt-hours by dividing by 1000. Finally, we multiply the result by the cost per kilowatt-hour ($0.10911) to get the cost per hour of running the appliance.
Amps (current) times volts = watts. so watts divided by volts = current (Amps). i.e.- 0.5 Amps.
Power is calculated by multiplying Volts x Amps, hence 60 Volts and 2 Amps will give 120 Watts. Energy is Power over a length of time. So if you use this device for say 2 hours you will consume 240 Watt Hours of Energy.
Current or AMPS are what the appliance draws or load of the appliance. So, if you have a say 10,000 amps going thru a cable rated for say 1,000 amps , guess what ,the cable over heats and either will melt or at least catch fire.
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
The answer to the question as phrased is yes, unless you run a factory in your house. 25kW is a substantial amount of power. However, you probably meant "how much energy is 25kWh?" This is about the amount of energy needed to run 25 electric kettles for an hour, or two electric kettles for a day. It's still quite a lot.
Power use of an electrical appliance is calculated by finding its rating in watts. The formula is W = I x E. Watts = Amps x Volts. <<>> Power is a general term. If you want to know how much you pay to power a certain appliance you need to figure out the amperage of the appliance, (usually located on the appliance itself or in the instructions). Power companies use kilowatt hours to charge you for electricity, to figure out how many kilowatt hours your appliance uses you would need to multiply the amperage your appliance uses by .115 and that would give you the kilowatts it is using. Then you would multiply that by how many hours you use said appliance and then multiply by your cost per kilowatt hour, (found on your electric bill).
1440 Watts
How much energy it uses
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 2.6 amps equals 624 watts. One horse power is 746 watts.
When you get your electric bill, look to see how many kilo watt hours (kWh) you used for the month. Then how much the bill cost. take the price divided by the (kWh). This is truly what your paying per (kWh). One (kWh) is 1000 watts being used for a hour, so one 100 watt light being used for 10 hours = 1 (kWh) or a 1500 watt hair dryer being used for an hour = 1.5 (kWh). so if your appliance power use is listed in amps, take amps x volts to figure out the watts. Plus determine how often the appliance runs. this will give You an idea of cost.
A device operating at 220 volts will consume half the current compared to the same device operating at 110 volts, assuming power output remains constant. This is because power (Watts) is the product of voltage (Volts) and current (Amps), so as voltage increases, current decreases to maintain the same power output.
