Adjustable power supply is widely used in the field of electronics. It is used to provide a constant voltage or current to a circuit. In this article, we will discuss the application and process of adjustable power supply.

1. Electronic testing – An adjustable power supply is essential for testing electronic circuits. It allows the user to adjust the voltage and current to match the requirements of the circuit being tested.

2. Battery charging – Adjustable power supply can be used to charge batteries. It helps to maintain a constant current and voltage during the charging process.

3. Audio equipment – Adjustable power supply is used in audio equipment like amplifiers, mixers, and speakers. It helps to regulate the voltage and current to prevent damage to the equipment.

4. LED lighting – Adjustable power supply is also used in LED lighting. It helps to provide a constant voltage and current to the LEDs.

The process of building an adjustable power supply includes the following steps:

1.Selecting the components - The first step is to select the components required to build an adjustable power supply. The components include a transformer, rectifier, filter capacitor regulator, and load.

2. Assembling the components -After selecting the components, the next step is to assemble them together. The transformer is connected to the rectifier which is then connected to the filter capacitor. The regulator is then connected to the filter capacitor and the load.

3. Testing - Finally the adjustable power supply is tested to ensure that it is working correctly. The voltage and current are adjusted to match the requirements of the load. Conclusion: In conclusion, adjustable power supply is an essential component in the field of electronics. It is used in various applications like electronic testing. battery charging, audio equipment, and LED lighting. The process of building an adjustable power supply involves selecting the components, assembling them together, and testing them to ensure that they are working correctly.
