Well, technically there would also be some inductance... which as an externally coupled field would radiate, and that inherently causes loss!

- chronolitus 6y agotomorrow's popsci headline: "Do barrels of water emit harmful 5G radiation? The answer may surprise you!"
- red75prime 6y agoAnd the loss will be in the form of gravitational waves.
- throwphoton 6y agoArgh is this real or not? Would energy radiated away as a result of inductance be analogous to energy radiated away by gravitational waves in the "water pressure analogy"?
- adammunich 6y agoI think so yes, but the effect would be very small
- majikandy 6y agoProbably more simply in kinetic and sound energy with water as it rumbles through the pipes and vibrates the pipes and barrels a bit.
- Nextgrid 6y agoI’m curious, how would you describe inductance in the context of the water analogy? I’m not very experienced in electronics so I’m hoping the “water version” of it might help me understand electric inductance better.
- jimmyswimmy 6y agoIt is the inertia of the water in the connecting pipes. In electrical systems, the inductance is that property of a component which tries to keep current constant. In both forms of the thought experiment, if you shut off the connection instantly, the voltage or pressure build to destroy the thing which stopped the connection. Water analogies only go so far. You would do well to pick up a book on basic electrical networks to learn this material further. Don't shy away from the math; it's really the only way to build the understanding that leads to intuition.
- ivanhoe 6y agoIn electric circuits capacity and inductance make energy oscillate between the electric and the magnetic field. The closest analogy I can think of for water pipes would be the oscillation between the kinetic and the potential energy (or the flow and the pressure). As for better understanding of inductance and magnetic field, imho it's better to stick to Faraday, Gauss and Lenz laws than looking for analogies, as EM field has it's very specific properties.
- ericye16 6y agoThere's a property called "inertance" which is analogous to inductance in electrical circuits: https://en.wikipedia.org/wiki/Inertance https://en.wikipedia.org/wiki/Inertance and it can cause things like water hammers: https://en.wikipedia.org/wiki/Water_hammer https://en.wikipedia.org/wiki/Water_hammer which are analogous to inductor sparks: http://web.physics.ucsb.edu/~lecturedemonstrations/Composer/Pages/72.54.html http://web.physics.ucsb.edu/~lecturedemonstrations/Composer/...
