How does laptop work on electricity?

A laptop operates on electricity by converting electrical energy from a power source, such as a wall outlet or battery, into usable power for its components. The power supply unit regulates the voltage and current to ensure that the CPU, RAM, storage, and other peripherals receive the necessary energy to function. The battery allows for portability, storing energy to power the laptop when not connected to an outlet. Overall, the efficient management of electrical energy enables the laptop to perform various tasks seamlessly.
