In my physics class, we have begun talking about potential difference, charge, resistance etc. While watching online videos for extra help on some clarification, I often hear that as electrons move through a resistor they lose some of their electric potential energy, creating a difference in voltage (v1 greater than v2). I noticed than in series when multiple resistors have been connected the resistors with higher resistance (ohms) have a greater voltage.
Does this voltage mean how much electric potential energy was lost, or something completely different? I know that potential difference refers to how much work a coulomb of charge can do when travelling from high to low potential, but how does this principle relate to before and after an encounter with one or more resistors in series?
Essentially, I don't really understand how potential difference functions across multiple resistors in series, and why a voltmeter produces the numbers that they do in a logical manner (not mathematically).
I have included an example picture to further show my problem:
