Why is the electromotive force of two cells higher in series
The electromotive force (EMF) of two cells is higher in series connection than in parallel due to the combined voltage of the cells. In series connection, the positive terminal of one cell is connected to the negative terminal of the other, resulting in the voltages of the cells adding up. This increases the total EMF of the series connection. On the other hand, in parallel
