A cell develops the same power across two resistance R_(1) and R_(2) separately. The internal resistance of the cell is

A cell supplies a current i_(1) trhough a resistnace R_(1) and a current i_(2) through a resistance R_(2) . The internal resistance of this cell is

Two cells of the same e.mf. e but different internal resistances r_(1) and r_(2) are connected in series with an external resistance 'R'. The potential drop across the first cell is found to be zero. The external resistance Ris

Two cells of the same e.mf. e but different internal resistances r_(1) and r_(2) are connected in series with an external resistance 'R'. The potential drop across the first cell is found to be zero. The external resistance Ris

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 cell of e.m.f E is connected to a resistance R_(1) for time t and the amount of heat generated in it is H. If the resistance R_(1) is replaced by another resistance R_(2) and is connected to the cell for the same time t, the amount of heat generated in R_(2) is 4H. Then the internal resistance of the cell is
