I have a 0 ohm resistor in series with the +5V power supply (as a provision to disconnect, if not needed). The power drawn by the connected circuit is 1A through this 0 ohm resistor. What should be the wattage of this resistor? Since there is no voltage drop across this resistor, can it be 0.1W or 5V * 1A = 5W? I am new to this stuff and hoping to get help from this great forum.
