Electric potential difference at the ends of a resistor

[QUOTE="greg_rack, post: 6407844, member: 672853"] So, having two parallel resistor ##R_{1}## and ##R_{2}## , the current flowing through the equivalent one will be ##I_{eq}=I_{1}+I_{2}##. Now, it comes the point I'm not totally getting: why is ##V_{eq}=V_{1}=V_{2}##? These V's are the difference of potential measured between which points? [ATTACH]271383[/ATTACH]referring to this ugly image representing the two parallel resistors: is ##V_{1}=V_{B}-V_{A}## or ##V_{1}=V_{D}-V_{A}##? Or, is ##V_{B}-V_{D}## since they're in the same conductor? As you can see, I think I haven't clear how does potential varies after that current passes through a resistor. [/QUOTE]
