I have a 12V DC 5A power supply and I would like to make a parallel circuit with a current division of 0.2A for the first branch and 4.8A for the second branch.  
I figured I need to use resistors, are 510 ohm and 22 ohm are the correct value ? What wattage should I use ?  

Latter on, I have to divide the second branch into 5 branches with equal amps, do I need resistors too ?
