Electricity consumption is measured in Kilowatt hours, this is one unit of electric consumption and charged according to your supplier.
You have to know how many watts your devices consume.
This is sometimes written on the ID tag or plate, or you can use a meter in line.
Multiply this wattage number by the hours it is switched on and this will tell you how much it has consumed.
e.g. A toaster may consume 1000Watts = 1Kw, if you ran it continuously for an hour it would consume 1 unit of electricity. Toasters don't run for more than a few minutes, so would use less than 1 unit per operation.
3 mins = 0.05hrs Therefore = 0.05 of a unit.
A 100W light bulb would consume 1 unit in ten hours.
100W = 0.1 KW. = one tenth of a kilowatt, so ten times this would equal 1 Kw/h, Therefore ten hours.

How to calculate the electrical energy for machine?
Electricity does not occur in natural state. It has to be generated by converting one form of energy into electric energy. The electric energy of any machine can be calculated by subtracting the all losses occurring in a machine (electrical, mechanical and magnetic) from total input power or energy.
Electrical energy is converted into work using electrical?
The correct answer is Electric motor. An electric motor is a device used to convert electricity into mechanical energy whereas an electric generator converts mechanical energy into electrical energy.
What is the output of an electric motor?
An electric motor converts electrical energy to kinetic energy.
What do electric cells do?
convert chemical energy into electrical energy
Which energy transformation is an electric fan?
electrical energy transforms into machenical energy.
How do electric companies calculate electrical energy?
Electric companies calculate the amount of electric energy by using special consumption meters.
What does an electric utility company do?
An electric utility company is a company that provides electricity to homes and businesses. An electric utility is responsible for the generation, transmission and distribution of electrical energy.

The electric motor converts electrical energy to?
An electric motor converts electrical energy to mechanical energy.
What electric energy converts to heat and motion?
Electrical energy can by converted to Mechanical energy (motion) by electric motors, and also electrical heaters change electrical energy into heat.
What are similarities and dissimilarities between a motor and an electric generator?
An electric motor converts electrical energy into mechanical energy. While an electrical generator does the opposite.
What energy does an electric fan use?
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
How do electric compainies usually calculate electrical energy?
They usually just measure current used and assume a known voltage.
What type of energy do motors change electrical energy into?
Most electric motors change electrical energy into rotational mechanical energy. A few electric motors change electrical energy into linear mechanical energy.
Electrical energy is converted into work using electrical?
The correct answer is Electric motor. An electric motor is a device used to convert electricity into mechanical energy whereas an electric generator converts mechanical energy into electrical energy.
Which electrical device change electrical energy into mechanical energy?
electric motor
The energy of moving electric charges are called?
