I am currently talking IB Physics and I’ve read the textbook, watched yt vids and asked my teacher but my head can’t seem to wrap around the concept of voltage.
Joules per coulomb, like what? Energy per charge? For what? How do we get there and how is it useful?
Any help appreciated :).

Voltage is also known as potential difference. Or to use another plumbing analogy, pressure. The higher the voltage the higher the ‘pressure’. It is a relative value of electrical ‘pressure’ relative to the general mass of earth (in electrical wiring).
When we create electricity we are doing two things, one creating a difference to earth in ‘pressure’. This is because it will always try to return to zero, no matter what, that’s why electric shocks occur as you become a path to zero. The other is current flow (amperage), that is how much is going to travel, or for example how much ‘electrons moving’ (more complex than that but it’s easy enough to think of it that way), through a wire.
Hope this helps!
It was explained to me this way, we are in still the very early days of understanding electricity, we can create it, control it and use it. But we are damned to still be able to fully explain the phenomena.
