A capacitor is conneted to a cell emf `E` having some internal resistance `r`. The potential difference across the

A resistor R is connected to a cell of emf e and internal resistance r. Potential difference across the resistor R is found to be V. State the relation between e, V, R and 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 emf 1.1 V and internal resistance r is connected across as external resister of resistance 10r. Find the potential difference across the external resistor.

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

Two cells with the same emf E and different internal resistances r_(1) and r_(2) are connected in series to an external resistances R . The value of R so that the potential difference across the first cell be zero is

Tow cells with the same emf E and different internal resistances r_(1) and r_(2) are connected in series to an external resistances R . The value of R so that the potential difference across the first cell be zero is

A lead resistance R is connected across a cell of emf E and internal resistance r. If the closed circuit p.d. across the terminals of the cell is V the internal resistance of the cell is.
