Can someone tell me why one never(?) sees the use of just one current-limiting resistor on the common side of the LED display, rather than one on each of the segment connections? It's not immediately obvious that it changes the current-hogging situation... does it?
Assume that an adequately rated resistor is selected to handle the worst-case 7x current.
