    Variable power supply is essential for any electronic hobbyist to begin their electronics lessons. For different applications you may need different voltages. So it becomes impossible to use multiple fixed power supplies all the time. 

    Also this variable power supply circuit ensures the protection of other circuit parts from voltage fluctuations. This supply unit uses a LM317 voltage regulator IC. By changing the value of potentiometer used in this circuit, the output voltage can be controlled easily. For safety, use this circuit to get a maximum of 30 volts.This product is brand of techkritya.

    Q1. What is full bridge rectifier?
    Ans1. A diode bridge is an arrangement of four (or more) diodes in a bridge circuit configuration that provides the same polarity of output for either polarity of input. When used in its most common application, for conversion of an alternating current AC) input into a direct current (DC) output, it is known as a bridge rectifier. 

    Q2. What is the role of LM337 IC?
    Ans2. The LM337 IC is a negative voltage regulator ICis able to deliver a maximum of 1.5 A at a range of 1.2 V to +30V.

    Q3. Where we can use this project?
    Ans3. We can use this is voltage adapters, SMPS and for providing variable voltage supply for running different devices and equipment's.

    Q4. What is the disadvantage of this project?
    Ans4. The disadvantage of this project is its voltage range is limited and fix and the current output is not sufficient for driving high power equipment's.

    Q5. What is the role of potentiometer?
    Ans5. Potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor.
