Electricity on Shabbat because of a burner

For the first question, when the circuit is designed to break down and rebuild itself by being turned on and off frequently, see the author on the subject who writes that the intention of the light switch is for it to stay on forever and only because of the bill of lading does he turn it off. I think that the author also knew that this is a narrow explanation, and also that it does not answer many cases (an air conditioner, for example).

Beyond this explanation of the prediction, I think that in a bed of parts, the bed itself, when it is built, also looks like it is made of parts for a fixed time. In contrast, in an electric circuit, although it can indeed be turned off, it does not appear that way when it is operating. There is no sign at the time of operation that the operation is temporary and composed of temporary elements. Therefore, in my opinion, there is room to see it as a permanent structure. Beyond that, in a bed of parts, there is also a bed that is not a bed of parts, and therefore the bed of parts is a bed of temporary elements. In electricity, this is its constant nature everywhere, it can always be turned off and on, and therefore it is more difficult to define it as temporary.

In your opinion, there is room for building simple circuits that will not be prohibited.
I think that according to the prediction, the whole point is whether there is a cancellation of the parts زلز or not, this is the point in the discussions on the issue of the staff of chapters in the taqiya and the other saharots do not play a role

I don't think so. Even in a simple circuit, the flow of current creates something new. A circuit that does not work at all is a different matter. This is definitely something to discuss.
The elimination of the parts is done by transforming them into a new and different whole. Therefore, I see no connection to the distinctions I made above.
