On increasing the current drawn from a cell, the potential difference across its terminals is lowered why?

Find the total current drawn from the battery?

Find the total current drawn from the battery.

Find the current drawn by the battery and the potential difference between A and B.

A circuit is shown in the diagram Find the potential differnce across the terminals of the battery.

A cell of emf 2 V and internal resistance 0.1Omega is connected to 3.9Omega external resistance. What will be the potential difference across the terminals of the cell?

Two cells of the same e.m.f. E but internal resistance r_1 and r_2 are connected in series to an external resistor R (fig. EP 3.25). What should be the value of R so that the potential difference across the terminals of the first cell becomes zero?

In the circuit show in the figure E,F,G and H are cells of e.m.f. 2,1,3 and 1 V and their internal resistances are 2,1,3 and 1Omega respectively. Calculate the potential difference across the terminals of each of the cells G and H.

The current flowing through a conductor and the potential difference across it two ends are as per readings of the ammeter and voltmeter shown below. The resistance of the conductor would be
