Under what condition the terminal potential difference across a battery and emf are equal?
Answer : The terminal potential difference across a battery and its electromotive force (emf) are equal when **no current is flowing through the battery**. This happens when the battery is **open-circuited**, ... a voltage drop, and the terminal potential difference will be less than the emf of the battery....

Why terminal potential difference is less than the emf of a cell?
Answer : The terminal potential difference of a cell is less than its electromotive force (EMF) due to the internal resistance of the cell. Here's why: 1. **EMF of the Cell**: The EMF is ... the voltage drop inside the cell, and therefore, the smaller the terminal potential difference compared to the EMF....
