I thought I understood the ground concept but now I'm a lot confused.
From: Pg.67 Practical Electronics for Inventors - Scherz Paul
As it's explained in the book, the first circuity is the one that's dangerous if someone would put a hand on the chassis while this person is grounded(or touching something that is). But the second one is safe. But grounding this circuity before the load wouldn't make the current go strait to the earth ground?
In the way I see, the second circuity is the same as the first when someone put a hand on the chassis, and as such, whatever the load is supposed to do, it won't work because there is no current passing through there.
Did I get something wrong???
