For a cell, the terminal potential difference is 2.2V, when circuit is open and reduces to 1.8V. When cell is connected to a resistance R=5Ω, the internal resistance of cell (R) is For a cell the internal resistance of cell (R) is the terminal potential difference is 2.2V when circuit is open and reduces to 1.8V.
