How The Power Supply Works

A power source is a device that converts other forms of energy into electrical energy and provides electrical energy to a circuit (electronic device).

The power source is based on the principle of "magnetism to generate electricity", which is generated from renewable energy sources such as hydraulic power, wind power, ocean tide, dam water pressure difference, solar energy, and burning coal, oil residue, etc.

Common power sources are dry batteries (DC) and household 110V-220V AC power.

Generators can convert mechanical energy into electrical energy, and dry batteries can convert chemical energy into electrical energy. Generators and batteries themselves are not charged, their poles have positive and negative charges respectively, and the positive and negative charges generate voltage (current is formed by the directional movement of charges under the action of voltage). It is only necessary to add voltage. When the two poles of the battery are connected to the conductor, the positive and negative charges are released in order to generate current. Dry batteries, etc. are called power sources. A device that converts alternating current into direct current through a transformer and a rectifier is called a rectifier power supply. An electronic device that provides a signal is called a signal source. The transistor can amplify the signal sent in front, and transmit the amplified signal to the circuit behind. For the following circuits, the transistor can also be regarded as a signal source. Rectified power supplies and signal sources are sometimes called power supplies.

A power supply is a device that provides power to electronic equipment, also known as a power supply, which provides the electrical energy required by all components in a computer. The size of the power supply, whether the current and voltage are stable, will directly affect the working performance and service life of the computer.
