A cell of constant emf first connected to a resistance R_(1) and then connected to resistance R_(2) . If power deliverd in both cases is same, then the internal resistance of the cell is

A cell of constant e.m.f. first connected to a resistance R_(1) and then connected to a resistance R_(2) . If power delivered in both cases is then the internal resistance o f the cell 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
