Theoretical questions with ideal components.(R2 is 10 Ohm)
1) parallel circuit. R1 and ammeter, 
If I have a parallel circuit of 2 resistances, both zero Ohm, the current would split to 2 and each current would be half. If the resistor R1 would be 1 pico Ohm, and the ammeter zero Ohm, there would be no current through the resistor, and all the current would go through the ammeter?
2) Ohms law. R2 is 10 Ohm, current is 1A. voltage between point A and B is 0 volt,
resistance between A and B is 0 Ohm,  according to Ohms law, I = V / R = 0 / 0 = 0 A. Correction, 0/0 is not 0, it is undefined.(edited after posting)
Is it telling me that it sees this as 2 circuits, with a common wire, and the circuit between A and B has no current, but the circuit between (+) and (-) has 1 Amp. Correction, the current between A and B is undefined. (edited after posting)
Both questions are theoretical with ideal components, and the voltmeter and ammeter are connected this way on purpose. I would like to get some feedback on this topic.


Question: Is there added value in having your own presentation layout and using it consistently?
Answer: I always appreciate when someone cares about their presentation. There are some things that are just inexcusable (e.g., tables that are left aligned on one slide and centered on another), and make you look lazy, so to the extent a consistent template would mitigate those then it can't hurt. 

My presentations tend to look the same and stand out against my peers. I do all of my writing in Markdown, analyses in R, and create dynamic presentations with some available R packages. Therefore, all of my graphs tend to have a style (ggplot2), tables look the same in HTML, fonts (and related consistencies between headings and body text) work together nicely. It's not just about the style of the presentation, as I know a few people who give presentations and have a very distinctive voice in their text, and a welcomed minimalism in slide content. 

I never thought too much about it, but I do have a "style" or "brand" in my presentations that most people who have met me and seen me present a few times recognize as clearly a presentation I crafted. However, this "brand" is really just me using a specific set of tools that most people don't use. What's the standard for most fields? Unfortunately Powerpoint, and some use the Mac Office Suite, while a few others use Prezi (and most use that tool poorly). 

There's a range of tools out there that you can utilize that might help develop a consistent "style" for you, but also will help to vastly improve your workflow, and also make your scholarship better (i.e., tools with an emphasis on reproducibility).

Whatever you do just do it well and make sure it works for you and our audiences.
