Unit of Electrical Energy. The unit of electric power is watt, and hence unit of electrical energy is watt – second since energy is the product of power and time. The watt – seconds is referred as joules. ... So one-joule electrical energy equals to the product of one volt, one ampere and one second.

The energy equal to one kWh is equal to one kilowatt, or one thousand watts, consumed for one hour of time. Amp-hours, abbreviated Ah or A·h, are a measure of electrical charge, and are often used to measure the charge of batteries. One Ah will supply one amp of current for one hour.

Watt is the unit of power whereas kilowatt-hour (kWh) is the unit of energy. Watt indicates the rate of using energy in J/s. ... If you have a Light bulb that has a rating of 100 watt, it means that the light bulb consumes 100 J per second. kWh is the unit of energy.
988000
Units of electricity are used to measure the amount of energy that has been consumed at a property. ... Therefore one unit of electricity is equal to one kilowatt hour (kWh) of electricity used. Your electricity supplier will charge you an amount in pence for each unit (kWh) of electricity used.

Watts are a measurement of power, describing the rate at which electricity is being used at a specific moment. For example, a 15-watt LED light bulb draws 15 watts of electricity at any moment when turned on. Watt-hours are a measurement of energy, describing the total amount of electricity used over time.

The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. An energy expenditure of 1 Wh represents 3600 joules (3.600 x 103 J).

Calculate Watt-hours Per Day However, electricity on your bill is measured in kilowatt-hours (kWh), not watt-hours. One kilowatt is equal to 1000 watts, so to calculate how many kWh a device uses, divide the watt-hours from the previous step by 1000.

Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).
