I have a 12 volt power source, I want to provide 700ma of current to a load.
R=V/I
R=12/.7
R=17ohms
Is this correct? I wasnt sure if I am supposed to use the source voltage, or try
to calculate the voltage after the resistor drops it to determine the current.
If I sound confused, please forgive me...
Thanks,
Andrew
