In a network as shown in the figure the potential difference across the resistance 2R is (the cell has an emf of E and has no internal resistance):

In a network as shown in the figure , the potential difference across the resistance 2 R is (the cell has emf E - volt and no internal resistance )

If the potential difference across the internal resistance r_1 is equal to the emf E of the battery, then

If the potential difference across the internal resistance r_(1) is equal to the emf E of the battery, then

According to this diagram , the potential difference across the terminals is ( internal resistance of cell =r)

According to this diagram , the potential difference across the terminals is ( internal resistance of cell =r)

A cell of emf E having an internal resistance r is connected to an external resistance R. The potential difference V across the resistance R varies with R as shown in figure by the curve: R

A cell of e.m.f E and internal resitance r ,is connected to an external resistance R. the variation of potential difference V across the resistance R as function of R as shown in the figure, is the best represented by curve

Calculate the potential difference across the 2k Omega resistor in the circuit shown in figure. The internal resistance of the cells are negligible.
