2023-01-30 How Does A Phone Charger Work?

A phone charger works by converting AC (Alternating Current) electrical power from a wall outlet into DC (Direct Current) electrical power that is compatible with the battery in your phone. The DC power is then used to charge the battery. The charger has a transformer that converts the AC power to the right voltage, a rectifier that converts the AC to DC, and a regulator that regulates the voltage to the right level for charging the battery.
