Adding external resistance option

[Naroek56]

For cell modelling it would be helpful to add a term that takes into account external series resistances such as tab weld resistances.
Would it be possible to add an optional resistance term to the simulation?

Thanks in advance!

If you just want to add the resistance to the voltage you can just post-process the voltage values by doing

V = solution["Terminal voltage [V]"] - R * solution["Current [A]"]

For more complex setups, you might want to use PyBaMM's sibling package liionpack (see https://github.com/pybamm-team/liionpack)

This is a relevant question, so I am converting it into a discussion.

For CV control it would be useful to have this as a pre-processing feature

Do we have an issue for this already?

Can we just add it here?
