PCB Design Rules

Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

What is the difference between PCB traces for carrying high voltage in comparison to traces carrying high current? Would there be any difference in how they are drawn? I'd preferably have an answer that would explain the constraints and limitations in simple words of a basic level.

As far as I can see, high voltage design requires more space between copper tracks and high current design requires wider tracks.

High voltage need wider track spacing, occasional slots in the board, conformal coating or potting and use better quality materials. While high current you use wider tracks and thicker plating and more vias and sometimes additional buses.
