## Introduction: 12v to 3v Voltage Regulator

You can easily step down any DC supply by just using 2 resistors. The voltage divider is basic and easiest circuit to stepdown any DC supply. In this article, we are going to make a simple circuit to stepdown 12v into 3.

## Step 1: Material Requires

12v battery x 1

1k ohm Resistor x 1

330-ohm resistor x 1

jumper wires

multimeter x 1

## Step 2: Schematic

A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics. we can create any small voltage respect to supply voltage by adjusting only one resistance.

## Step 3: Practical Aproach

Our task is to stepdown 12v into 3v. so, we are going to use 1k ohm resistor and 330-ohm resistor.

Connect one end of 1K ohm resistor to 12v supply and second to any other hole of breadboard.

## Step 4:

Frome same hole connects one end of 330-ohm resistance and another end to the ground.

## Step 5:

Connect 12v supply

## Step 6:

From the junction of both resistor connect one 3v LED.

## Step 7:

To verify Connect multimeter to the junction and measure the output voltage

## Step 8:
