If that is what works for you for now, it's okay. The more you'll investigate, the more you will understand how voltage is often compared to water flow force.I find the fact that the voltage across the different components in a parallel circuit is the same, counter intuitive because I expect the parallel circuit to split the voltage, as it does the current. But I guess what everyone is trying to say with the water analogy is, if the tap is opened, this is the current flowing. The voltage is just the force/push, that moves the current. The part I find counter intuitive is that if a force is being shared by three avenues, then that force is still being divided up and lessened.
I just read from your link that the defining characteristic of a parallel circuit is that all components are connected between the same set of electrically common points. So, I guess I need to think in terms of, the voltage just being a reading of a force that doesn't actually travel. It is just a measure of the effect that the resistance is having on the current, taken at any two given points in a circuit. And as all components are connected between the same set of electrically common points in a parallel circuit, then by this definition, the voltage must therefore be equal across those points. Maybe!
