Book Free Demo1. Five cells, each of emf E and internal resistance r are connected in series. If due to over sight, one cell is connected wrongly, then the equivalent emf and internal resistance of the combination is
2. A circuit whose resistance \(R\) is connected to \(n\) similar cells. If the current in the circuit is the same whether the cells are connected in series or in parallel, then the internal resistance r of each cell is given by
