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!

The way I understand it and think of it is this.
We measure electricity in different ways.
Think of volts like how much pressure is behind it, think of amps as how much volume is available, and the ohms is the measurement of resistance.
Watts is a relation of Amps x Volts and is used to measure consumption.
Look at a house in the US. The electrical outlets in say the bedroom are typically 120v/15A circuits. If I plug in an alarm clock, it is designed to operate at 120v of pressure, but consumes very little capacity (0.1A) making it only consume maybe 12W of the total 1800W provided on that circuit.
To break it down with a plumbing analogy. A bedroom circuit might be a kitchen faucet. The line from the meter might be a garden hose (same pressure, more volume), a high power line by the road might be a fire hose (high pressure high volume), a taser might be like a power washer (super high pressure, very little volume).
And consumption is measured in watts (GPM). Since 12v @ 1A = 12w and 1v @ 12A = 12w. It’s like getting the same gallons per min out of a small hose at higher pressure as a larger hose at lower pressure.
Hope my ramblings don’t confuse you more.
