Power Supply

Power Supply is a critical component of any electrical or electronic system, providing the necessary electricity to power the system's components. Understanding power supply is essential for anyone working with electrical or electronic systems, from engineers and technicians to hobbyists and students.

What is Power Supply?

Power supply refers to the process of providing electrical energy to electrical or electronic devices. It involves converting electrical power from one form to another, such as from AC to DC or from one voltage level to another. Power supply systems are designed to meet the specific electrical requirements of the devices they power.

Importance of Power Supply

Reliable and efficient power supply is crucial for the proper functioning of electrical and electronic systems. Power supply issues can lead to system failures, data loss, equipment damage, and even safety hazards. Understanding power supply enables individuals to design, install, and maintain electrical and electronic systems that are safe, reliable, and efficient.

Applications of Power Supply

Power supply has numerous applications in various industries and fields, including:

• Consumer electronics (e.g., computers, smartphones, TVs)
