Text Solution

AI Generated Solution

To understand why the electromotive force (emf) of a cell is greater than its terminal voltage, we can break down the explanation into several steps: ### Step-by-Step Solution: 1. **Definition of EMF and Terminal Voltage**: - The electromotive force (emf) of a cell, denoted as \( E \), is the maximum potential difference when no current is flowing. - The terminal voltage \( V_T \) is the potential difference across the terminals of the cell when it is supplying current. ...
