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

In the given circuit, if the potential difference across the internal resistance r_1 is equal to E, then the resistance R is equal to:

In the given circuit, if the potential difference across the internal resistance r_1 is equal to E, then the resistance R is equal to:

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
