Battery/ Power Supply

1. Battery: A battery is a portable device that generates electrical energy through chemical reactions. It consists of one or more electrochemical cells that convert stored chemical energy into electrical energy. Batteries are used to power a wide range of devices, from small electronics like smartphones and laptops to larger systems such as electric vehicles and grid storage solutions. They provide a convenient and portable source of electricity for both primary (non-rechargeable) and secondary (rechargeable) applications.

2. Power Supply : A power supply is an electronic device or system that provides electrical energy to a load or circuit. It converts electrical power from a source (such as AC mains or a battery) into the desired voltage, current, and frequency required by the load. Power supplies can range from simple adapters for charging devices to complex units used in industrial machinery and telecommunications equipment. They ensure stable and reliable operation of electronic systems by delivering consistent electrical power according to specific requirements.
