More specifically, I understand what they are (Voltage is the guide of electricity and Current is the speed of the flow), but I’m having trouble understanding their relation. For example: in a hypothetical scenario where I have a 220v source that outputs 1amp through an uncovered wire, since the voltage is only the guide of electricity, would it be safe to touch?
I also may be wring about the definition of Voltage and Current all together.
All help is appreciated! THX!
(I’m 14 and learing about electronics on the internet. English is also NOT my first language)

The Voltage *U* is the electric potential.
You can make an analogy with a waterfall.
When water reaches the top of the waterfall, it has a lot of *potential energy*. That energy will be converted to *kinetic energy* (which is tied to speed) as it falls down.
Voltage is the same, but it’s the potential energy of electric charges.
The Current *I* is like the flow of your waterfall: how much water goes through it.
So Voltage is always measured between two points. You need to know how high your waterfall is in regards to the bottom of it.
