Eli5 how does playing around with different metrics of amps, ohms, and volts alter how powerful electricity is?

Think of electricity like water through a hose. The current (amps) is the amount of water you are putting through the hose. The voltage is how hard you need to push to get that amount of water through the hose. The resistance (ohms) could be the size of the hose pipe you use.
Current, voltage, and resistence are related by the simple equation V = I x R, voltage equals current multiplied by resistance. This means we can work out what happens when we change these numbers.
Back to the water hose. If you increase the current (amount of water flowing) but keep the size of the hose pipe the same, what happens? You need to push a harder to get more water through the same size pipe (I.e. voltage increases).
What if you keep the voltage the same but make the hose pipe thinner? The thinner pipe increases resistance, so you get less current through the pipe!
