4 a A few identical cells are first joined in series and then in parallel Under what condition will both the combination send the same current though the external resistance R b In a closed coil there are n number of cells connected in series E M F of each cell is e internal resistance r and the connecting wires are resistanceless What reading will the voltmeter give when connected across any one of the cells Assume that the voltmeter has infinite resistance
