- Homework Statement:
- Calculate the circuit's current and pd across a component

- Relevant Equations:
- Ohm's law

Here are a few problems I have been trying which are shown below

Here is what I have done

The correct answers for these Q's are:

I'm not sure what I have done wrong for Q4, I assumed that all 12 cells were connected in series thus each individual emf sums up to 24V

Similarly the internal resistances must sum up to 7.2 ohms

Is there anything that I am missing for me to get a current value of 5 amps instead of 3 amps?

Any help would be really appreciated! Thanks
