Default Mismatched voltage wired in parallel. What is resulting voltage?

Fundamental questions.

Given:

If I wire two 3V 1mA batteries in parallel, the result is 3V 2mA.


---
No, it isn't.
---

If I wire two 3V 1mA batteries in series, the result is 6V 1mA.


---
No, it isn't.
---

BUT:

1. What happens if I wire the following in parallel:

3V 1mA
6V 1mA


---
The 6V battery will discharge into the 3V battery until there is no
voltage difference between the batteries.
---


2. And similarly, the following in series:

3V 1mA
3V 2mA


---
Nothing.
---

Does #1 above average the voltage to 4.5V?


---
No.
---

Does #2 above average the current to 1.5mA?


---
No. There will be no current until a load is attached.

Thanks!

It's time for everyone to just step back, take a deep breath,
relax, and stop throwing hissy fits over crossposting.

**** you.

Since when are you the moderator here who can tell _everyone_ what
to do? Just ask your stupid questions, wait for your answers, and
then just go away instead of trying to run the show.

What was your reason for your last comment? Is there something I
missed? You had given good answers 'til then. Possibly his comments
were aimed at Phil who was playing jackass - if so you missed the
target.


One of my rotating signatures is the comment above about relaxing about
crossposting. For some reason he equated this with an attempt at
self-establishing myself as a moderator or something. Agree or disagree
with my signature, and that's fine, but sputtering that kind of childish
crap got him killfiled.
