Internal resistance understanding

Click For Summary
SUMMARY

The discussion centers on the concept of internal resistance in electrical components, particularly batteries. Internal resistance directly impacts the current flow and the terminal potential difference (pd) of a battery. Key formulas for calculating resistance, voltage, potential difference (pd), electromotive force (emf), and current are essential for understanding these relationships. Aakeen seeks clarity on how internal resistance influences these electrical parameters.

Hello,
I'm having difficulty trying to understand internal resistance of any component. I don't understand how exactly the internal resistance affects the current and what exactly is the terminal pd?

And for calculating resistance, voltage, pd, emf, current and all those basic things - what are the basic formulas that could help?

Thanks,
Aakeen
