Introduction: Adjustable Power Supply Using Diodes

About: Share diy projects to those who have the same hobby with me

Hii friend,

Today I am going to make Adjustable power supply circuit using 1N4007 diodes.This circuit is very easy to make and it is very cheap.

Let's get started,

Step 1: Take All Requirement Parts As Shown in the Picture

Required parts -

(1.) Diode - 1N4007 x7

(2.) LED - 3V x1

(3.) Digital multimeter x1

(4.) Power supply - 5V DC

Step 2: Solder Diodes

Solder all 7- diodes in series as shown in the picture.

Step 3: Now Connect the Power Supply Wire

Connect 5V power supply to the circuit.

Connect +ve wire of power supply to +ve side of diode.

and connect -ve wire of power supply to -ve side of diode.

Step 4: Now Give Power Supply to the Circuit

Now give 5V DC power supply to the circuit and measure voltage in different-different points of diodes using digital multimeter.

Observation - Now we observe the potential difference at different-different points of diodes is changes.

Step 5: Give a Load

Now check the circuit by connecting a load.

As in the picture I connect a LED in different-different points of diodes and I observe that LED glow in different-different amount as you can see in the images.

This type you can make an adjustable power supplier circuit using diodes.

What do you think about this circuit tell me in the comment box now.

Thank you
