Chemical energy to electrical energy.
how do I convert my electric wall sconce to battery operated
A battery is a device that can convert electrical energy into chemical energy for storage. In a battery, chemical reactions occur that release energy in the form of electricity when needed.
No. There are, indeed, ways to convert mechanical energy into electrical energy, but a battery is not usually designed to do this. You can convert mechanical energy to electrical energy by another device, but the battery itself has to be charged by electricity.
You cant.
In a battery, the energy is stored as chemical energy, if that's what you mean. The exact details depend on the type of battery.
use a transformer.
A battery
A battery or a fuel cell converts chemical energy directly to electrical energy
A cellphone battery converts chemical energy into electrical energy. When the battery is connected to a device, the chemical reactions within the battery generate the flow of electrons that powers the device.
A battery-powered torch converts chemical energy stored in the battery into electrical energy, which is then converted into light energy when the circuit is completed and the bulb is illuminated.
A battery undergoes a chemical reaction to convert stored chemical energy into electrical energy. This transformation allows the battery to power electronic devices by delivering a flow of electrons through a circuit.
Such conversions are often inefficient and/or expensive. It requires an external power supply or battery charger to convert AC into DC.
