I'm trying to clear up my picture of basic electricity and electronics. I've looked at some other posts that ask what is voltage, but have come away with questions in my mind. Here are some thoughts I'm throwing out there in the area of current energy, speed, and force. I feel there are some principles and factors that aren't acknowledged when I study this area. Does resistence to a current affect the quantity and speed of the electrons passing a point? How does the speed and quantity of the current affect the output into appliances and its uses/how is this characteristic utilised? (voltage might resolve this question) Where is the offload of energy by a current into an appliance and output, so it returns to complete the circuit carrying with it less energy? It is never explained like that. Why don’t we see a difference in speed after an electric current has entered something and exits to complete the circuit or/and do the electrons slow down as they go through a resistor, coming out the other end slower? I have seen simulators that suggest otherwise. Why does a current come out of an appliance and resister the same speed as it went in, shouldn’t some energy be used? This is never written beside circuit diagrams and explanations. Is it an issue of force applied, why aren't watts and connection to the concept of power used more often? Is this where e.m.f occurs in a way similar to Newton mechanics, force applied with a resulting speed depending on the mass, thus in electricity the effect of some input force has varying results on the amount of resulting current and speed. I don't find this kind of breakdown and wording. Perhaps some of my wording of these particular points is unconventional. Dare I say it but I feel there are gaps in the language and explanations of the foundations of electricity from the ones that I've seen. I feel a lot of this has to do with ohms law, voltage, e.m.f. and potential difference and I've read definitions of all these things and feel I have a decent understanding, but can anyone help clear up some of the points I've raised, or suggest some good material or tutorial that addresses this better. Thanks for reading my post.
