The discussion revolves around the mechanisms by which an electromotive force (EMF) device maintains a potential difference and charge within a circuit. It touches on concepts related to electrical fields, the role of terminals, and the forces involved in both chemical reactions and magnetic forces.
Participants express uncertainty regarding the specifics of how chemical reactions contribute to forces, and there is no consensus on the details of these mechanisms. Multiple viewpoints regarding the nature of forces in EMF devices are present.
Some limitations include a lack of detailed understanding of chemical reactions and their relationship to forces, as well as the dependence on definitions of terms like "force" and "potential difference." There are also unresolved questions about the continuous charging of terminals.
This discussion may be useful for individuals interested in the principles of electromotive force, the operation of batteries and generators, and the interplay between chemistry and physics in electrical systems.
Yes. There is a force which keeps the terminals charged and maintains a potential difference between them. This force originates from chemical reactions in a battery or magnetic force in a generator.esha said:are these terminals charged so as to maintain an electrical field and if they are charged who is keeping them charged continuously?
I don't know much about chemical reactions and resulting forces. You can post in the general physics or chemistry forums for further details.esha said:how does chemical reactions originate forces? they can release or absorb energy. isn't it?
