Total Current Increase when Cells Connected in Parallel

In summary, when connected in parallel, the total current drawn is divided amongst the cells, while in series, each cell experiences the same current. This can be further understood by looking at Ohm's law and knowing the voltage of the parallel cells.

When the cells are connected in parallel, what happens to the total current drawn when compared with the arrangement that the cells are connected in series?

That looks like something you could easily look up in textbook. Have you tried that?

Look up Kirchoffs laws and Mesh and node analysis. It should all be in the textbook

Then, say, when 3 cells of 1.5 V are connected in parallel with a fixed resistor, will the total current drawn be larger than the cells connected in series? Why?

Have you tried posting something useful up, you sarcastic prat.

When in parallel the current is shared in each component according to (V/Ri)

Whilst in series equal current goes through each component

Dirac.

I don't consider things that prevent a person from learning to be "useful". Being handed answers only prevents a person from learning how to do it himself. Your attitude has consistently been "Please help me trick my teacher into giving me a passing grade without actually having to learn anything." I don't understand why you bother.

What is the voltage of the parallel cells?

What does Ohms law tell you about the current?
 

What is the concept of connecting cells in parallel?

Connecting cells in parallel means that the positive terminals of multiple cells are connected together, as well as the negative terminals. This allows for the cells to work together to produce a larger total current.

How does connecting cells in parallel affect the total current?

When cells are connected in parallel, the total current increases. This is because each cell contributes its own current, and the total current is the sum of all the individual currents.

Why is connecting cells in parallel useful?

Connecting cells in parallel can be useful for increasing the total current, as well as ensuring a more stable and reliable power source. It also allows for the cells to share the workload, potentially prolonging their overall lifespan.

What happens to the voltage when cells are connected in parallel?

When cells are connected in parallel, the voltage remains the same for each individual cell. However, the overall voltage of the circuit may decrease slightly due to the increased current.

Are there any downsides to connecting cells in parallel?

One potential downside of connecting cells in parallel is that if one cell fails, it can bring down the entire circuit. Additionally, if the cells have different internal resistances, it can lead to uneven distribution of current and affect the overall performance of the circuit.
