power = voltage x current, power has nothing to do with time. Electrical energy is power x time.
so at 110 volts *household current, power = 110 x 12 = 1320 watts
and energy = 1320 x 8 = 10,560 watt-hours or 10.56 kilowatt-hours

A 60 Watt appliance is plugged into a 120 Volt AC outlet How much current is the appliance drawing when it is turned on?
Amps (current) times volts = watts. so watts divided by volts = current (Amps). i.e.- 0.5 Amps.
How much energy is 60 volts and 2 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.
Your appliance draws 1.43 amps at 10911 per kilowatt hour how much does this appliance cost you per hour?
To answer this question I have to know what you are charged per Kw/hr by the power company. If you mean .10911 per kw/hr, then I need to know at what voltage.
Why is it dangerous to pass to much current through the mains cable?
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.
What formula do you use to determine the amount of energy used by an appliance?
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).
How much power is 25 kilowatts and would that be able to sustain an average Household for an entire day?
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.
In a home has 120v service there is an electric appliance that a risistance of 12 how much power will this appliance consume?
1440 Watts
What does the power rating for an appliance tell us?
How much energy it uses
What are the difference in energy consumption using a 110 volts to a 220 volts?
The energy consumption for the same appliance the power consumption in watts would be the same watts = volts X amps. In general if an appliance requires 10 Amps @ 110V then it would only require 5 amps @ 220V In general in an a North American house the appliances that run on 220V are on 220 because they would pull too much power to be logically wired on 110V. So they do pull more power than most 110V appliances.
How much horsepower in 2.6 amps?
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.
How do you calculate the monthly running costs of electrical appliances?
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.
How many watts solar panel do you need to charge my 12v 100amp battery in 6 hours if you use 5.5amp a hour?
There is too much information there. Charging a 100 amp-hour battery fully would take 18 hours at 5.5 amps, or 6 hours at 16.67 amps. At 5.5 amps the power would be 12x5.5 or 66 watts, and this is the rating of the solar panel required. That would be about 0.4 of a square metre.
