Answer:
battery is a device that converts chemical energy directly to electrical energy.
LEARNING OBJECTIVES
Describe the functions and identify the major components of a battery
KEY TAKEAWAYS
Key Points
A battery stores electrical potential from the chemical reaction. When it is connected to a circuit, that electric potential is converted to kinetic energy as the electrons travel through the circuit.
The voltage or potential difference between two points is defined to be the change in potential energy of a charge q moved from point 1 to point 2, divided by the charge.
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
