FAQs on Cells in Series & Parallel Video Lecture - Physics for JEE Main & Advanced

1. What is the difference between cells connected in series and cells connected in parallel?
Ans.Cells connected in series are arranged end-to-end, which increases the total voltage while the current remains the same as that of a single cell. In contrast, cells connected in parallel are arranged side-by-side, which increases the total current capacity while the voltage remains the same as that of a single cell.
2. How do you calculate the total voltage of batteries in series?
Ans.To calculate the total voltage of batteries in series, you simply add the voltage of each cell together. For example, if you have three 1.5V batteries in series, the total voltage would be 1.5V + 1.5V + 1.5V = 4.5V.
3. How do you calculate the total current of batteries in parallel?
Ans.To calculate the total current of batteries in parallel, you add the current ratings of each cell together. For instance, if you have three batteries rated at 2A each connected in parallel, the total current would be 2A + 2A + 2A = 6A.
4. What are the advantages of connecting batteries in parallel?
Ans.Connecting batteries in parallel increases the overall current capacity and provides a longer operating time for devices, as the load is shared among the batteries. Additionally, if one battery fails, the others can continue to supply power.
5. Can you use batteries of different voltages in series or parallel configurations?
Ans.It is not recommended to connect batteries of different voltages in series or parallel configurations, as this can lead to imbalanced charging and discharging, potentially damaging the batteries. It is best to use batteries of the same voltage and capacity for optimal performance.
