I came across this problem in a book and I admit becoming a deer in the headlights  :grr

I remember looking at the answer and not liking it  :grr though I do not recall

Initially I proposed that current can only flow in one direction and when the cathode end is negative then current will flow.

But the cathode end is also connected to ground  :grr sooooo how's it gonna be negative  :grr

I welcome as usual any advice hints speculation solutions discussion etc

The good news is I'm going to construct this circuit I have a few transformers and can put some low voltage like 6 to 12 volts on the secondary  xP

I'm still a bit hesitant to ground one terminal of the secondary  :loco

But that's the good thing is i can simply build it and not take chances like have a fuse etc

And that's what I like is I don't have to stare at something for days trying to make sense of it or accept it when I have the components and test equipment to actually see what happens  :tu:

The cathode is not grounded.  Think about how an inductor reacts to AC.
The question is a bit misleading as it implies there will be DC at the cathode, I would not call it exactly that.
