Hi all.
I need to learn a little electronics math.
Here's what i'm trying to do:
I am supplying a circuit 14 volts DC supply voltage. This circuit will draw up to about 10 amps peak, and will draw around 4 amps continually while in use.
What i would like to do is reduce the voltage to this circuit to around 12 volts DC or so (not critical) using a resistor in series with the power input.
I cannot reduce the voltage at it's source as it is powering other circuits that do need the 14 volts.
so i am looking for the value of the resistor i might want to use, and how many watts it will need to handle.
something tells me i may be going about this the wrong way by trying to add a resistor in series.
If that is true, will someone please show me the error of my ways, and a better way to accomplish my goal.
thanks for any and all input.
