New General Theory Of Electrical Action
In 1839, Michael Faraday was still at it. This was when he proposed a new and truly general theory of electric action, specifically in regards to how it acts within the body. He felt that electricity was caused by specific tension to be created in matter. When the tension was rapidly relieved then what occurred was a rapid repetition of cyclical buildup and breakdown. The buildup of tension passed along a substance like a wave.
Of course, such known substances he referenced were called conductors. Faraday had already referenced Electrochemistry in former work. He felt that not only was this part of it to consider, but it needed to be further studied. In the electrochemical processes, the rate of buildup and breakdown of a strain was equal or close to equal to the chemical affinities of the substances involved.
However, the current is not a material flow but, rather, a wave pattern that Faraday proposed regarding tensions and relieving them. Insulators, to Faraday, were materials whose particles could take a lot of strain before snapping. When adding in an electrostatic charge in an isolated insulator, we simply measure the accumulated strain. Therefore, if all was presented correctly then all electrical action was the result of forced strain in our human body.
