I have a 400 watt power supply that i have converted to a Bench power supply (bought power supply for $11 :P) but anyway.. i need some help controlling the amperage it exerts.
and i would like to be able to use 16-24v 2-5 amps (for my (secret)Project) and mabey still use my original voltages/amperages
i have seen voltage controllers through google but thats not exactly what im asking for. just less amperage. and i know about ohms law and how it will affect my voltage.
Ohm's law will determine the amount of current that will flow. Unless your supply is a constant current source, the current that will flow will be dependant on the voltage and the load.
If you are wishing to limit the amount of current being given to a load, like when powering an LED, then simply add a current limiting resistor in series.
You know that your circuit will only draw the amount of current it needs, right? That is, if you have a 1000A supply and your circuit is rated at 1A, the circuit will only draw 1A not be blown up by 1000A.
