The EMF of a cell is always greater than its terminal potential difference when the cell is discharging. 2. During the charging of a cell, the terminal potential difference is greater than the EMF of the cell. 3. The internal resistance of a cell is independent of the concentration of the electrolyte. Which of the statements given above is/are correct?
Options:
- A: 1 and 2 only
