The resistances are different but the current stays the same.



By Ohm’s law, V = IR. The voltage must be conserved because it’s simply the electrical equivalent of potential energy. Therefore, current and resistance are inversely proportional and less resistance = greater current.

And yeah, it is definitely the engine for the one above.
