why are cells connected in parallel?

Answer 1

For devices that really consume the watts, you connect cells in parallel so that the individual cells last longer.
Cells connected in parallel. The voltage across the cell combination is always the same and the total current from the combination is the sum of the currents in the individual cells. Cells or batteries connected in parallel have their like terminals connected together. The overall voltage remains the same but the capacity is increased. For example, if two 12-V automotive cells were connected in parallel, the overall voltage for the cells would still be 12 V. However, the connected cells would have twice the capacity of a single 12-V battery.

this is the reason why the cells are connected in parallel ....

hope this answers your question

Answer 2

Are you asking about batteries (voltaic cells)?

Voltage supplies in series add, so placing batteries in series increases the potential drop (I.E.: placing two 3 volt batteries in series makes a six volt battery).

You wire batteries in parallel if you want more electrical current, at the same voltage, without draining the batteries too fast.

For devices that really consume the watts, you hook batteries in parallel so that the individual batteries last longer.

Answer 3

It depends on what you want to get from the cells...
