A temporary source of an electric current is called a battery. It converts chemical energy into electrical energy to power devices or circuits.
The potential energy of an electric fan is typically in the form of electrical potential energy. This energy is stored in the fan's electric circuit when it is connected to a power source.
energy is because it has a power source like every other energy
An electric whisk produces mechanical energy by converting electrical energy from the power source into rotary motion to mix and aerate ingredients.
The primary energy source for a bike is the rider's muscular energy, which is generated through the consumption of food and the body's metabolism. As the rider pedals, this energy is converted into mechanical energy that propels the bike forward. In the case of electric bikes, an additional energy source is provided by a rechargeable battery that powers an electric motor to assist with pedaling.
