How cell phone chargers work

First, you need to understand how the charger works and some physical knowledge about electricity, so it is easier to understand how it works.

Charge

Charging is a Chinese term that refers to recharging batteries and other equipment. The principle is to let the direct current pass from the opposite direction of discharge to restore the active material in the battery. It has extended meanings such as study, work, etc.

Charger

A charger is a device for charging other electrical appliances. It adopts high-frequency power technology and advanced intelligent dynamic adjustment charging technology. Using power electronic semiconductor devices, the alternating current with constant voltage and frequency is converted into direct current. Chargers can be divided into industrial frequency machines and high-frequency machines according to the working frequency of the designed circuit. They can be divided into ordinary chargers, battery chargers, solar chargers, and hand-cranked chargers according to use. Chargers are widely used in various fields, especially in life. They are widely used in common electrical appliances such as mobile phones and cameras.

Voltage

Voltage, also known as potential difference or potential difference, is a physical quantity that measures the energy difference of a unit charge in an electrostatic field due to different potentials. Its magnitude is equal to the work done by the unit positive charge moving from point A to point B due to the force of the electric field, and the direction of the voltage is defined as the direction from high potential to low potential. The international unit system of voltage is volt (V, referred to as volt), and the commonly used units are millivolt (mV), microvolt (μV), kilovolt (kV), and so on. This concept is similar to "water pressure" caused by high and low water levels. It should be pointed out that the word "voltage" is generally only used in circuits, while "potential difference" and "potential difference" are generally used in all electrical phenomena.
