What are the advantages and disadvantages of connecting batteries in series? In parallel?

Connection in series is simpler and you can increase the voltage, while in parallel connection the voltage remains the same and if any cell breaks, other elements still work

See the step by step solution

Step by Step Solution

Step 1: For batteries in series.

Batteries connected in series have the following advantages:

1. It requires only one wire and is easy to set up.

2. The voltages add up if you need a higher voltage.

3. They do not overheat because the current is smaller due to larger internal resistance.

4. If something is damaged, it is immediately detected because everything stops working.

5. The current is the same through all elements.

Batteries connected in series have the following disadvantages:

1. When an element stops working, everything stops working.

2. the resultant internal resistance of the battery is high.

Step 2: For batteries in parallel.

Batteries connected in parallel have the following advantages:

1. in parallel combination, the resultant internal resistance of the battery is reduced. Thus, current increases.

2. if one cell stops working, it will not affect the working of others.

Batteries connected in parallel have the following disadvantages:

1. It overheats more easily because the resistance is smaller.

2. Additional cells increase the amount of current.

5. We cannot change the voltage by adding new cells, in parallel.
