Question

how internal resistivity of an electrolyte depends upon temperature? 2.If Emf is the amount of work done to bring 1c charge from positive to negative end why it is called as a force?

Answer 1

An Electric Cell or Battery is a power generating device which generates an Electromotive Force in between it’s two terminals. Along with the the developed EMF , an electric cell and battery also have some internal resistance , which in-tern effect’s it’s terminal voltage.
A detailed descriptions of these parameters of a battery and cell are given below.
