let us suppose i have a device whoose rating is 12v, 0.3A and my supply is of 24V. For the device to work should i limit current to 0.3A by connecting a resistor of 80 ohm or should i limit the voltage by converting 24v to 12v?

limit current or voltage for a device? (noob)

Reduce the voltage, don't limit the current...
