I like to use a water tower connected to a pipe as an example of how electricity works.

Electricity depends on voltage AND current. If you think of it like a water supply then the voltage would be like the pressure in the pipes due to the height of the water tower. The current would be like the speed with which the water flows through the pipes and that is determined by the resistance, which we can think of as the size of the pipe. If we make the pipe bigger, that is, decrease the resistance, then the water flows faster. If we decrease the resistance in an electrical circuit then the current increases. That is why you often hear the term current used for both electricity and water flow.

For more technical details please see my answer to the question about resistance. "If a fuse will melt.."
