Editing 2571: Hydraulic Analogy

Electric flow is [https://www.youtube.com/watch?v=Lvp_a_JkD2o commonly represented] by a "{{w|hydraulic analogy}}". In this analogy, the water pressure represents {{w|voltage}} and the flow of the water is the {{w|electric current|current}}. {{w|Electric resistance}} is represented by a constricted section of a pipe.

[[Miss Lenhart]] is teaching a class and starts to explain this analogy when [[Cueball]] suddenly has an idea and changes her diagrams - connecting the electrical diagram and the hydraulic diagram. In doing this, he has envisioned what comes to be called a "liquitricity device", combining liquid water and electric current flows together and given a suitably {{w|portmanteau}} title.

The last panel shows that Miss Lenhart and Cueball eventually receive the {{w|Nobel Prize}}, presumably the {{w|Nobel Prize in Physics}}, for the design ''and construction'' of the device - indicating that rather than being purely theoretical it has actually been practical to make this device.  

The title text 'explains' how this device works and references {{w|Ohm's Law}}, one of the fundamental laws of electricity, but strangely seems as much an incomprehensible mix of the two as the diagram in explaining whatever form of {{w|Wave–particle duality|possible duality}} it actually employs.

[[Randall]] already mixed water flow and circuit diagrams over 10 years ago: one of the [[Footer comics|footer comics]], [[730: Circuit Diagram]], displays a ''very complex'' circuit diagram. Although no pump or direct water flow can be found here, it all ends up in a beaker with holy water. And there is a symbol labeled 3 liters, at the bottom close to the beaker. This is the symbol for an orifice or flow restriction used on plumbing or hydraulic diagrams.

:[Miss Lenhart and Cueball, holding the marker pen down, stand on either side of the white board looking at Cueball's version with the merged diagram. He has connected the two, so instead of the wire going down after the resistor in the circuit diagram, it now is connected with water flowing to the right just below the resistor, and then up into the pump to the right of the resistor. At the bottom where the water pipe before bent up into the pump, the water now continues running to the left (the pipe was not drawn around it by Cueball), and it now flows where the bottom part of the wire, from the circuit, was before, turning up below the battery and connecting with it there. All the labels from before have been retained as follows.]
