Forty-eight (48) hours is equal to two (2) days, 2,880 minutes, or 172,800 seconds.
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

Kilowatt hours (kWh) is a unit of energy equal to the consumption of one kilowatt of power for one hour. It is commonly used to measure electricity consumption and is found on utility bills to indicate how much energy has been consumed over a period of time.
Electricity is measured in units called kilowatt-hours (kWh). One kilowatt-hour is equal to the amount of energy used by a 1,000-watt appliance in one hour. Utility companies measure the electricity consumption of a household or business in kilowatt-hours to determine how much to charge for electricity usage.
Kilowatts are a measure of electrical power. Kilowatt hours are a measure of how much electrical power has been used.
about 3,000,000 kilowatt hours.
about 3,000,000 kilowatt hours.
40 watts for 24 hours is 40 x 24 watt-hours, or 960 watt hours which is 0.96 kilowatt-hours, equal to 0.96 Unit, which costs about £0.12.
1 kilowatt is equal to approximately 1.34 horsepower.
1 ampere is equal to 1000 milliamperes.
The energy transferred can be calculated by multiplying the power (2400 watts) by the time (1 hour = 60 minutes): Energy = Power x Time. 2400 watts * 1 hour = 2400 watt-hours. To convert watt-hours to kilowatt-hours, divide by 1000: 2400 watt-hours / 1000 = 2.4 kilowatt-hours. Therefore, 2.4 kilowatt-hours of energy is transferred when a 2400 watt washing machine is used for 60 minutes.
The iron uses 1.2 kilowatts (1200 watts) in one hour, so it uses 2.4 kilowatt hours in two hours.
Commonly this figure is used for battery used for cars or UPS. 100Ah means, you can draw 100 Ampere current for one hour. Like a battery 0f 12Volt,7Ah can be used for a circuit which draw current of 1 Amp. can be used for approximately 7 hours.
