The battery is a device that consists of one or more electrochemical cells with external connections for powering electrical appliances. When there are multiple batteries in a given circuit, they are either wired in parallel or series connection. Understanding the difference between series and the parallel connections is crucial as they determine how batteries perform in different applications. In this article, let us look at batteries'' series and parallel connection and when each method is appropriate.
Batteries can either be connected in series, parallel or a combination of both. In a series circuit, electrons travel in one path and in the parallel circuit, they travel through many branches. The following sections will closely examine the series battery configuration and the parallel battery configuration.
Similarly, if r1, r2, r3 are the internal resistances of individual cells, then the internal resistance of the battery will be equal to the sum of the internal resistance of the individual cells.
Wiring batteries in series provides a higher system voltage resulting in a lower system current. Low current indicates that you can use thinner wiring and suffer less voltage drop in the system.
A set of batteries are said to be connected in parallel when the positive terminals are connected together, and similarly, the negative terminals of these cells are connected. These combinations are referred to as parallel batteries.
If the emf of each cell is identical, then the emf of the battery combined by n numbers of cells connected in parallel is equal to the emf of each cell. The resultant internal resistance of the combination is,
Batteries can be connected in a mixture of both series and parallel. This combination is referred to as a series-parallel battery. Sometimes the load may require more voltage and current than what an individual battery cell can offer. For achieving the required load voltage, the desired numbers of batteries are combined in series to achieve the current needed, and these series combinations are connected in parallel.
Batteries power our modern lives, from smartphones to electric vehicles. However, the way these batteries are connected—whether in series or parallel—can significantly impact their performance. Understanding these configurations is essential for making informed decisions, especially when designing systems for energy storage, electronics, or renewable energy solutions.
This article explores the key differences, benefits, drawbacks, and practical applications of connecting batteries in series versus parallel. By the end, you''ll have a clear understanding of which configuration is better suited for your needs.
In a series configuration, the positive terminal of one battery connects to the negative terminal of the next. This arrangement allows the voltages of each battery to add together, while the current remains the same.
In a parallel configuration, all positive terminals are connected, and all negative terminals are connected. This setup increases the system’s capacity (amp-hours), but the voltage remains constant.
