But how do these converters work and can we even build one by ourselves.

## How do you step down 12v dc to 5V DC?

Connect 12 v to pin 1 ,pin 2 is the ground and pin3 gives 5v. Don’t want to use IC or not getting it,use a voltage divider using 2 resistors and you are done with it. Connect 12 v across the series combination of 4.7k ohm and 6.8k ohm(readily available standard ) resistor and take the output across 4.7k ohm.

## How do you halve voltage?

To divide voltage in half, all you must do is place any 2 resistors of equal value in series and then place a jumper wire in between the resistors. At this point where the jumper wire is placed, the voltage will be one-half the value of the voltage supplying the circuit. The 5V is now 2.5V. VCC is split in half.

## How do you reduce voltage from 12V to 10v?

To drop voltage from 12V to 10.5V using resistors then you can use 2 resistor in series. R2/(R2+R1) × 12V = 10.5V.Solving the equation gives:R2=7×R1.Therefore if you choose R1 to be 4.7kOhm, R2 wil be 33kOhms.

## Do resistors reduce voltage?

Resistors don’t reduce current and voltage instead it opposes flow of current and produce drop in voltage across the terminals.

## How do I lower my power supply voltage?

To reduce voltage in half, we simply form a voltage divider circuit between 2 resistors of equal value (for example, 2 10KΩ) resistors. To divide voltage in half, all you must do is place any 2 resistors of equal value in series and then place a jumper wire in between the resistors.

## How do I reduce 12V to 6v?

It’s possible to step 12 volts down to 6 volts by incorporating a pair of 10,000-ohm resistors into the circuit. Cut two lengths of wire, and strip each wire of 1/2 inch of insulation at each end. Attach one end of the first wire to the positive terminal on the power supply.
