Pls correct me I have no idea. When there is a negative and positive and ground in a diagram I dont know what to do

Look at your other 16 posts. That should give you an idea.

Robert_kidd I'm just tryna learn man. I saw on diagrams that the in between of two 9v cells is ground and I tried to simulate that. I'm really just trying to learn

I know you are. It’s not always clear what you want to know. A bit of advice though, ditch the voltmeters if you are using the oscilloscope as well. They can make a circuit look crowded and more complicated than it might actually be.

You can put the ground at any point in the circuit. It just means that any voltage measurements you make are with respect to that ground point. So, if you have a 9V battery and you connect ground to the positive then that is effectively your zero point and you have a minus 9V supply at the other terminal. Don’t know if that helps ?

On your circuit above, clear the voltmeters, replace the diodes with, say, 1k resistors. Connect ground to junction of the two resistors. You now have a plus and minus 2.5V supply.

No problem. What does confuse me is that when an answer is suggested, above for example, you don’t seem to modify the circuit to see what happens??
