SUMMARY
The discussion clarifies the representation of batteries in circuit diagrams, specifically the notation of a long vertical line (positive) followed by a short vertical line (negative) for a single cell. It explains that a series of long and short lines with dots signifies a battery composed of multiple cells. A dry cell typically has an electromotive force (Emf) of 1.5 volts, while a wet cell, such as those in car batteries, has an Emf of 2 volts. The combination of multiple cells in series results in higher voltages, such as 9V from six dry cells or 12V from six wet cells.
