Not really.its obviously a different kettle of fish.
In the real world where most of us reside, a circuit requires at a minimum, 2 conductors to complete.It doesn't need a ground to operate
No, it does require ground.It doesn't need a ground to operate, you can send it to a negative 5 as well if you want.
Right. For current to "flow" it requires a closed loop. There is no loop from the lower right connection point (post #5, second picture) to gnd.The one as a circuit, seems to have no current going to the ground there, it looks like a dead wire.
Yes we can. +5 V is the positive pole, 0V (ground) is the opposite pole.you cant have +5 volts without -5 volts!
Of course it is. Read what I wrote:is that setupable in real life??
Ground is only not shown in the simulator's schematic, it is implicitly assumed to be present. In real life you need to make a physical connection as shown in post #10.Ground is the reference potential (0V) for the simulator. Even if you don't see it in the schematic.
I think it's time you gave some serious thought to taking up fishing or playing bowls as you just seem completely unable to grasp even the simplist basics.I still dont understand.
Can you please demonstrate me an example of using +5v and ground in real life?? I'm totally confused about it.
