PCB has lipo battery input Vcc and GND. The motor connected to PCB will draw max 30A. While trying to allocate plane for Vcc and GND a question came to my mind as which one is more important for current draw.
I have inner 0.5oz layer and outer 1oz layer.
My questions are:
1)Should i allocate 1oz outer layer for Vcc and inner layer for GND or viceversa.
2)Or since there will be a return current are they both equally important for current handling (for example even if i allocate enough copper area for Vcc and poor area for GND will this be a problem due to return current).
3) If we draw 30A from Vcc, is the return current also 30A.
