I am asking this question because at first I thought that this concept was pretty clear to me, but it is not. So, my first question:
- Is potential difference only a property of an electric field? If not, what is it?
- Does the physical nature of any conductor(like shape or size) effect the potential difference between 2 points in the conductor?
- When current flows through a circuit and when charges are traversing through the circuit, why do we say there is a potential drop? Isn't it constant?
Now, I move on to asking some more things about potential difference, but this time including resistors. I completely understand that when resistors are placed in series, the total resistances is the sum of all individual resistances. But, I am not able to understand this:
- Why is the sum of potential difference between the end points of the resistors equal to the total potential difference? Can someone explain this to me in a more intuitive way? (I request the readers to throw some more light on this)
- Why do we say that current flowing through each resistance is the same? Is it not logical enough that in the conductor, the parts with lower resistance will have a higher current flow? Because if this is true, by Ohm's law we can get each resistor's resistance value to be same, even though I used different resistors!
I request the readers to provide the answers to all my 5 questions, I really need these answers. And, please explain each question individually.
