What effect does connecting battery cells in series have on total voltage?

Increases total voltage
Decreases total voltage
No effect on total voltage
Reduces voltage to zero

The correct answer is: Increases total voltage

Connecting battery cells in series results in an increase in total voltage. When two or more cells are connected in series, the voltage of each cell adds up. For example, if you have two batteries, each providing 1.5 volts, connecting them in series will produce a total voltage of 3 volts. This method of configuration is commonly used in various applications where higher voltage is needed than a single cell can provide. This principle is foundational in electrical circuits and is utilized extensively in designing battery packs for devices such as RVs, where specific voltage levels are necessary to ensure proper functioning of electrical systems. The arrangement allows for the efficient use of space and materials while achieving the desired output voltage. Understanding this concept is crucial for technicians working with RV electrical systems, as it directly impacts the performance and safety of the entire system.
