But how do these converters work and can we even build one by ourselves.
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.
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.
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.
Resistors don’t reduce current and voltage instead it opposes flow of current and produce drop in voltage across the terminals.
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.
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.
