Discussion Overview
The discussion centers on the feasibility of creating an electric field in water using electrodes with a voltage difference of 10-15V, while avoiding electrolysis or arcing. The context includes practical applications and experimental setups, particularly in salty water environments.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant inquires about the possibility of generating an electric field in water without electrolysis, suggesting the use of insulated electrodes.
- Another participant recalls using an electric field mapping apparatus in a laboratory setting, noting the formation of small bubbles at the electrodes, which they associate with electrolysis.
- A subsequent reply emphasizes the importance of avoiding bubble formation, which is linked to electrolysis, and seeks alternatives to achieve the desired electric field.
- A participant mentions that colleagues conducted measurements on oil pipes underwater, concluding that a much lower voltage (around 0.2V) was necessary in that specific salty water context.
- Another contribution states that electrolysis does not occur below 1.7V, but above that threshold, electrolysis will happen if current flows.
Areas of Agreement / Disagreement
Participants express differing views on the voltage levels required to avoid electrolysis, with some suggesting that higher voltages lead to electrolysis while others reference practical experiences that indicate lower voltages may be necessary. The discussion remains unresolved regarding the optimal conditions to create an electric field without electrolysis.
Contextual Notes
There are limitations regarding the specific conditions under which electrolysis occurs, including the dependence on water salinity and electrode insulation. The discussion does not resolve the mathematical or experimental parameters necessary to achieve the desired outcome.
