SUMMARY

When cells are connected in parallel, the total current drawn increases compared to when they are connected in series. This is due to the fact that in a parallel arrangement, the current is distributed among the components according to the formula (V/Ri), where V is the voltage and Ri is the resistance of each component. In contrast, in a series configuration, the same current flows through each component, resulting in a lower total current. Understanding these principles is essential for analyzing electrical circuits effectively.

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

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?
