What:

"Voltage is like water pressure in a pipe while. "Watts," the unit of measurement, is like the number of gallons of water flowing through a pipe."

What:

"The charges are like water in a stream or pipe.

The current is how much water is flowing through the stream or
pipe at some place.

Voltage is like the height of the stream or pipe. Naturally, the water will flow from a high place to a low place.
To get it from a low place to a high place, you must put energy into it, either using a pump, or a lot of buckets.
Once there, the water has a lot of energy. As it flows back to the low place, the energy will be changed into sound (think of a waterfall), heat (friction of the water on the stream bed) or motion of leaves or other things the water might hit."

What:

So if voltage is like water pressure, it can be related to the height of a stream or pipe that contains water. Water pushes down on itself. Think about diving in the ocean or a deep pool, the deeper the dive the higher the water pressure, the more your ears begin to tingle.

Any how, this water and it's pressure it not static, it will move via gravity. The rate of water movement is analogous to the current.

What:

"Ohms Law: Ohm's Law is given by V = IR, where I is the current,V is the potential difference measured across the resistance and R is the resistance of the conductor in Ohms. A resistor is like a water wheel: it slows down the flow of water but turns it into work (heat). A battery is like a pump. It moves water uphill to a certain elevation (voltage). Likewise, a voltage drop is like a drop in elevation."

What: "Voltage in an electrical circuit is like pressure in a water system. To say that voltage flows through a circuit is like saying that pressure flows through a pipe. Pressure can push water through a pipe, and it is correct to say that water flows through a pipe, but it is not correct to say that pressure flows through a pipe. The same is true for voltage. Voltage will push current through a wire, but voltage cannot flow through a wire. Voltage is often considered to be the potential to do something. For this reason it is frequently referred to as potential. Voltage needs to be present before current can flow, similar to how pressure must be present before water can flow."
