A 33 watt fluorescent tube consumes 33 watt-hours of electricity per hour. It means it uses 0.033 kilowatt-hours (kWh) of electricity in one hour.
The average home fluorescent lamp consumes 40W of power. Running for one hour it will consume 0.04 KWh. Units of electricity are charged per Kilowatt hour.
If you have an average TV set e.g. 32" consuming 150 watts power, one hour would take 150 watt-hours of energy, that is 0.15 units, which would cost between 2p and 3p in the UK.
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.
The amount of electricity used per day is measured by the watt-hour meter.The electricity consumed depends on the following factors:-Power Factor(p.f) of the load.Amount of load.
The amount of electricity a plugged-in lamp uses depends on its wattage. A typical 60-watt bulb, if left on for one hour, uses 0.06 kilowatt-hours of electricity.
A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWH) of electricity.
One hour at 60 mph
1,000 watts
As much energy it takes to move your ass!!!!!
A 12W downlight uses 12 watts of power per hour when it's running. To convert this to kilowatt-hours (kWh), which is how electricity is typically billed, you divide by 1,000, resulting in 0.012 kWh per hour. Therefore, if you run the downlight for one hour, it will consume 0.012 kWh of electricity.
If you are driving at the rate of 50 miles per hour, it will take you one hour to drive 50 miles.
