What makes this confusing to some reading this thread is the missing piece of information. The Algabra.

V=IxR Or spoken "Voltage equals current times resistance"

V=volts (Potential)

I=Amps (Current)

R=Ohms (Resistance)

Note: Impeadance is resistance when the circuit is on.

To think about this as flow through a pipe to visualize.

V=pressure

I=flow rate

R=size of the pipe. Large R = small pipe. Inverse relation.
