Question

What is the EMF of a dry cell?

Answer 1

1. The question asks us to calculate the EMF of a dry cell.
2. As a first step, one should understand what a dry cell is.
3. A dry cell is a type of electric battery that can be used in portable electrical devices.
4. A paste electrolyte is used in a dry cell with enough moisture to allow current flow.
5. We already know that emf, or electromotive force, can be defined as the electric potential produced by a changing magnetic field or an electrochemical cell.
6. A zinc-carbon cell, also known as a dry Leclanche cell, is a very common dry cell. It has an estimated emf of $1.54V.$
