What Is Internal Resistance? How A Battery Works?

That explanation is how a battery ideally works. Internal Resistance. Resistance can be defined as an object''s ability to hinder the flow of electrons passing through a conductor. Resistors are made of insulators, such as carbon or plastics, materials that forbid the flow of electrons through them. This ability is credited to their structure.
