A student measures the terminal potential difference `(V)` of a cell (of emf `epsilon` and internal resistance `r`) as a function of the current `(I)` flowing through it. The slope and intercept of the graph between `V` and `I`, then respectively, equal

A student measure the terminal potential difference (V) of a cell (of emf internal energy is connected in providing the circuit is

A cell of emf epsilon and internal resistance r is charged by a current I, then

The curve between current (i) and potential difference (V) for a photo cell will be

A straight line plot showing the terminal potential difference (V) of a cell as a function of current (I) drawn from it, is shown in the figure. The nternal resistance of the cell would be then-

A cell of emf 'E' and internal resistance 'r' draws a current 'I'. Write the relation between terminal voltage 'V' in terms of E, I and r.

In an experiment a student measures terminal potential difference (TPD) of a cell. When the same cell is connected to an external resistance of 5 Omega then the TPD is 2 V and when the same is repeated for an external resistance of 10 Omega then the TPD is 2.4 V. What is the emf and internal resistance of cell?
