How do electric companies calculate electrical energy?

Electric companies calculate the amount of electric energy by using special consumption meters.


What is Einstein's equation that us used to calculate the amount of energy produced from a given amount of mass?

E = mc^2


How is Albert Einstein's equation Emc2 important today?

The equation, E = mc2, is important today because it is the basic equation of nuclear physics. So for example it is used to calculate the amount of energy produced by the fuel in a nuclear power station, or the amount of energy potentially released in a hydrogen bomb. It is also important is astrophysical models of stars, where energy is provided by nuclear fusion. The equation is used alot in particle physics to calculate the masses of particles produced and to calculate the the energy needed to produce particular particles.


A kitchen blender transforms electrical energy into mechanical energy Why is the amount of mechanical energy produced less than the amount of electrical energy used?

Losses are due to inefficencies of the motor, and friction on moving parts.

What is Emc2 used for?

E = mc2 is used to calculate how much energy is produced when you convert matter to energy. The variables stand for E = Energy, m = mass, and c = speed of light. If you do the math correctly, you will see that a very small amount of mass will generate a very large amount of energy. The equation can be used to calculate the energy of an atomic bomb or a nuclear power plant where mass and energy are converted.


What is the equation that defines energy?

There are different types of equations to calculate different types of energy.
