EXPERIMENTS: DETERMINATION OF THE INTERNAL RESISTANCE OF A CELL (2) To determine the internal resistance of a cell AIM: APPARATUS: METHOD: Leclanche cell or Daniell cell, key, milliammeter, resistance box, connecting wires. PSITY OWO DENT mA B Connect the cell in series with the key, the milliammeter and the resistance box R. for suitable values of R. obtain the corresponding values of the current I. Tabulate your readings. QUESTIONS 1. Plot 1/1 against R. 2. Measure the slope and the intercept on the 1/1 axis. 3. Assuming that 1/-R/E++/E where r is the internal resistance of the cell and E is the emf of the cell with the key open, determiner and E from the graph. 4. State two precautions taken to ensure accurate result.​
