Do resistors in series have the same voltage across them? As I know that resistors in parallel do have the same voltage. Also in which circumstances do we could I use the potential divider formula?

Resistors in series share voltage in a ratio based on their resistance. E.g. a 20ohm and a 10ohm resistor would share 12v 8 and 4v respectively.

When in series, current is the same, when in parallel, voltage is the same. So you'd only need to use the potential divider formula when in series.
