4.7: Electromotive Force and Internal Resistance
Show that this can also be written as (frac{ER}{R+r}). The reader is reminded of the following definition from section 4.1: Definition.The potential difference across the poles of a cell when no current is being taken from it is called the electromotive force (EMF) of the cell.. I shall use the symbol E for EMF.. Question.
21.2: Electromotive Force
We thus use the name electromotive force, abbreviated emf. Emf is not a force at all; it is a special type of potential difference.

EMF of a Battery: Understanding the Electromotive Force
The emf of a battery refers to its electromotive force, which is the energy source that drives the flow of electric current in a circuit. It is a measure of the potential difference between the positive and negative terminals of a battery, and is commonly expressed in volts (V). In this topic, we will explore the concept of emf in batteries and …
