Power output / Power input * 100 = %Efficiency For instance, 746 watts is equivalent to one horsepower. If an electric motor were 100% efficient, a 1HP motor would only draw 746 watts of electricity. Look in any motor catalog, and you will see that typical 1HP motors draw around 1100 watts. So: (746 / 1100) * 100 = 67.8% The example motor has a 68% electrical efficiency. You can apply the same formula to any electrical device - heaters, amplifiers, Transformers, etc.

What kind of energy is produced by battery?
Electrical energy.
Does a battery contain chemical energy?
Yes, a battery contains potential chemical energy.
The battery's electrical energy was transformed into another form of energy name the energy?
electromagnetic energy?
What energy sources uses chemical energy to produce electrical energy?
a battery.. got it off study island bby :)
What is used to store potential electrical energy?
A Battery or a capacitor.
What energy do batteries give?
electrical, chemical, heat, and light energy
What is a form of energy that travels from a battery?
chemical energy
Is a battery a electrical energy?
Yes, battery is a electrical source.
What happens after chemical energy from a battery turns into electrical energy?
The electrical energy provides power. When the chemical energy is depleted, the battery will not longer generate electrical energy.
How do you call the energy inside the battery?
battery has chemical energy which is converted into electrical energy by the battery........
Physics principle of the battery invention?
Chemical energy in the battery is turned into electrical energy when the battery is hooked up to an electrical circuit.
What type of energy is a batery that runs a moving toy?
The battery "is" not energy; it's a battery. The battery has chemical energy stored. When moving a toy, the battery releases electrical energy; i.e., some of the chemical energy in the battery is converted to electrical energy.
Is electrical energy in a torch?
Yes, the chemical energy from the battery is converted into electrical energy.
What device can turn electrical energy into chemical energy?
A rechargeable battery. (The battery in your cellphone, or the one in your car.) When it's empty, you connect it to a source of electrical energy. The battery stores the electrical in the form of chemical.
A battery converts chemical energy to?
In a battery, the energy transformation is: chemical energy -----> electrical energy.
Do solar panels store energy?
No, they only transform light energy to electrical energy. If they are connected to a battery the battery will be able to store the electrical energy.
Chemical energy from a battery is changed into electrical energy this electrical is then changed to which type of energy?
physical energy
