Detailed Solution

The positive pole of the battery is marked with a plus sign (+) and the negative poles with a minus sign (-).
Cells are the basic electronic elements that supply electrical energy to the power board. By combining the number of cells, we can create a larger power unit. This larger device is called a battery. By connecting the positive pole of one cell with the negative pole of the other, we can increase the number of cells. This series continues the design of a larger power source known as the battery.
