Can anyone tell me what junctions, branches, as well as loops are in physics given the following diagram? Thanks so much!

    I'd like to know the exact difference between junctions, branches and loops reflecting on the diagram uploaded.

    They are basically the same as graph theory in mathematics. You need to redraw the diagram in familiar terms

    what makes this complicated is that there is not one circuit, but two parts to this circuit

    Exactly. This is not "according to the textbook" problem you need to improvise with certain degree of flexibility.

    cool so , now that we have rearranged your diagram, how many junctions do you think there are (i.e where the current flows in separate routes)?

    eliminate c, A F and G from the diagram, they are only there to confuse, that is what makes it a problem

    the only problem is that bottom line! in particular that resistor between the two batteries. One solution is Combine the batteries into one battery, and let the resistor in the middle be a series resistor

    here is my final analysis: there are 2 loops between AB and AD. There are 3 branches (where current goes) B to A B to C and B to D. I can only see two loops for the current ( between the batteries) from 10V battery to 10V battery and from 80V battery to 80V battery.

    Juntions? this is where the current splits off, again kirchoff's theory reduces this, as I have. I would say there is only one junction (B) which splits the current

    I guess I am one of them( I mean I corrected my physics lecturer who said that a capacitor was charged in 2/3 of the time--> I showed mathematically it was never charged), so cant really say anything bad about them

    Physics is contaminated with intuitive reasoning and lack of mathematical justifications.

    Physicists in general are lackadaisical about numerical computations and they rely mostly on fully comprehensible concepts which are the foundations of our reasoning. If you know what I mean..

    Sad fact is physicists estimate from intuition too much. However I do believe physics is the fundamental science that aids us in understanding as well as becoming logical of our self. Too many people reason terribly due to naivety in fundamental logics. I mean you see those people everywhere making absurd claims of how an ideal person should be without knowing all the philosophical as well as physical concepts behind them. They say experience automatically makes one wise but that's a big no no. Understanding of physics and maths makes him wise and not the sole activity of existing without much mental venture.

    I personally believe education should be catered to physics and less on tireless root memorization which relies of obsessive tendency of people to actually repeat them over and over without being conscious of the methodical learning.

    If you understand physics everything else (being able to read/write/articulate/reason/justify/argue/) secondary because the nature of this subject necessitates them.

    Take for example when we do physics our attention is applied to the profoundly complex thought which necessitates automatization of other foundational academic skills whose process of mastery is wasted over years after years when in fact understanding of physics fixes all these problems in light speed. Education other than math/physics is a mere means to demonstrate your stupidity in the studies of public service.
