The figure shows a plot of terminal voltage 'V' verus the current 'I' of a given cell. Calculate from the graph (a) emf of the cell and (b) internal resistance of the cell.

A cell of emf epsilon and internal resistance r is connected across a variable resistor R. Plot a graph showing variation of terminal voltage V of the cell versus the current I. Using the plot, show how the emf of the cell and its internal resistance can be determined.

For a cell, the graph between the potential difference (V) across the terminals of the cells and the current I drawn from the cell is as shown in figure. Calculate the e.m.f. and the internal resistance of the cell.

Explain the meaning of the terms e.m.f., terminal voltage, and internal resistance of a cell.

For a cell, a graph is plotted between the potential difference V across the terminals of the cell and the current I drawn the cell. The emf and the internal resistance of the cell are E and r, respectively. Then

Maximum current produced by a cell of emf 10 V and internal resistance 2 Omega is

For the determination of emf E and internal resistance 'r' of a cell , the graph is obtained between potential difference V between the terminal of the cell against the current l, which was changed by adjusting the rheostat, is as shown . The internal resistance of the cell is

The plot of the variation of potential difference across a combination of three identical cells in series, versus current is as shown in figure. What is the emf and internal resistance of each cell?

The plot of the variation of potential difference across a combination of three identical cells in series, versus current is as shown in figure. What is the emf and internal resistance of each cell?

When a celll is connected to an external resistance R_(1) , current through it is i_(1) . When the same cell is connected to an external resistance R_(2) , current through it is i_(2) . Calculate the emf and internal resisance of the cell.

The terminal voltage is (E)/(2) when a c urrent of 2A is flowing through 2Omega resistance, then the internal resistance of cell is:-
