f cells are placed side by side. Then, how are the terminals of the cells connected?

To connect cells placed side by side, we typically follow these connection principles:

1. Series Connection: In a series connection, the positive terminal of one cell is connected to the negative terminal of the next cell. This setup increases the total voltage while keeping the current the same.

   • Example: If you connect two batteries (each 1.5V) in series, the total voltage becomes $1.5V + 1.5V = 3V$.

2. Parallel Connection: In a parallel connection, all positive terminals are connected together and all negative terminals are connected together. This setup keeps the voltage the same while increasing the current capacity.

   • Example: If you connect two batteries (each 1.5V) in parallel, the total voltage remains $1.5V$, but the overall capacity (amp-hours) is doubled.

Summary

• For cells placed side by side, they could be connected in either series or parallel configuration, depending on the desired effect on voltage and current.
