Hmmmm...a rectifier on each leg, that would be two diodes, right? That's
not the Graetz configuration i know of (4 diodes). I think you eliminated
half of the wave.

I'am afraid I disagree: you MUST use an always connected resistor too
discharge the cap!!!
And for safety you let the cap shake hands with your largest screwdriver!

AC: simple, fast problem-solving
DC: independent of 50/60 Hz wave
Take your pick!
