I have been looking around for an easy way to convert 12V to 5V. I have seen some people saying that a simple resistor is all that is needed.

Volts = Ohms * Amps
Amps  = Volts / Ohms
Ohms  = Volts / Amps

$$ Volts = Ohms \cdot Amps $$ $$ Amps = \frac{Volts}{Ohms} $$ $$Ohms = \frac{Volts}{Amps}$$

So applying a resistor will diminish the voltage of the circuit. That should mean that an appropriately sized resistor could simply be placed in the path of a 12V circuit, converting it to 5v.

  • If this is the case how would one reduce amps?
  • Would series vs parallel make a difference in this area?

I have seen designs that include a regulator IC and some capacitors, but if a simple resistor/fuse/diode setup will do the trick, I would really prefer that.

That should mean thatSo applying a resistor will diminish the voltage of the circuit... That should mean that an appropriately sized resistor could simply be placed in the path of a 12v12V circuit and convert, converting it to 5v...

also if this is the case how would one reduce amps? would series vs parallel make a difference in this area?
