Hi,
How exactly does the "+ v -" notation for specifying the voltage across a component (e.g. a resistor) work? Is the + side always oriented towards the + side of the voltage source, so that it's just a mnemonic for remembering what direction current goes in, or is there some deeper meaning? Will exchanging + and - result in a nonsensical schematic?
