Cells in Series and in Parallel: When multiple cells are connected together in a circuit, they can be connected either in series or in parallel. In a series connection, the cells are connected one after the other, such that the positive terminal of one cell is connected to the negative terminal of the next cell. This means that the same current flows through all of the cells, but the total voltage of the circuit is equal to the sum of the voltages of the individual cells. For example, if three cells with a voltage of 1.5V each are connected in series, the total voltage of the circuit would be 4.5V.
In a parallel connection, the positive terminal of each cell is connected to the positive terminal of all the other cells, and the negative terminal of each cell is connected to the negative terminal of all the other cells. This means that the same voltage is across all of the cells, but the total current of the circuit is equal to the sum of the currents of the individual cells. For example, if three cells with a current of 1A each are connected in parallel, the total current of the circuit would be 3A.
There are several advantages to connecting cells in series:
There are several advantages to connecting cells in parallel:
There are several disadvantages to connecting cells in series:
Complex design: Connecting cells in series can be more complex than connecting cells in parallel, as it requires careful consideration of the characteristics of each individual cell to ensure that the voltage is distributed evenly and that the overall circuit operates correctly.
There are several disadvantages to connecting cells in parallel:
Increased cost: Connecting cells in parallel often requires additional components, such as additional wiring, connectors, and protection circuits, which can increase the overall cost of the circuit.
