How do you calculate energy in an appliance?
Once you have those three bits of info, here’s how to calculate the cost:
- Calculate the daily energy consumption: (Wattage) x (hours used per day) Divide the answer by 1,000.
- Calculate the annual use: (Daily energy consumption) x (number of days the appliance is used per year)
- Multiply #2 by your energy cost.

What is the energy equation?
The equation developed by Albert Einstein, which is usually given as E = mc2, showing that, when the energy of a body changes by an amount E (no matter what form the energy takes), the mass (m) of the body will change by an amount equal to E/c2.

What is energy in electric circuit?
Electrical energy is the product of power multiplied by the length of time it was consumed. So if we know how much power, in Watts is being consumed and the time, in seconds for which it is used, we can find the total energy used in watt-seconds. In other words, Energy = power x time and Power = voltage x current.
