From where the E inside the battery comes from?

[kashan123999]

So as I am junior high school student just learned that when the terminals of wire are connected to a battery,an E (electric field) is established inside the battery from positive to negative end/terminal (How did I assumed one as positive and one as negative? COnvention regarding electric fields,am i right?),Work is required to push say,positive charges from negative terminal to positive terminal i.e against the electric field (WHY? obviously to build potential/potential difference b/w both ends) so the work is done by the energy provided by the battery,When positive end would be have charges and negative end do not have them...obviously the current would start to flow from positive to negative terminal...all of this is actually conventional current..

My question is,from where the Electric field inside the battery comes from?

The EMF is present inside the battery before any external circuit is connected. Have a read through this introductory article at wikipedia:

thank you i would surely read it as well :)

The redox chemical reaction moves the ions to their respective terminals creating an electric field and potential difference. Once charges accumulate at the terminals, the redox process is propelling ions to move against the electric field. This increases the voltage at the terminals (potential difference) as well as increase the E field energy. Did I help?

The electric field inside a battery is created by the separation of charges within the battery. When a battery is manufactured, a chemical reaction takes place that separates positive and negative charges within the battery. This separation of charges creates an electric field that runs from the positive terminal to the negative terminal. This electric field is what allows the battery to produce a potential difference and provide energy to a circuit.

As for the convention of labeling one terminal as positive and the other as negative, it is simply a convention that has been established in the scientific community. This convention helps us to understand the direction of current flow and the direction of the electric field within a circuit.

Overall, the electric field inside a battery is a result of the chemical reactions that occur during its manufacturing process. This electric field is essential for the battery to function and provide energy to a circuit.
