I'm started newly to studying electrical engineering and I really finding it hard every time I solve and deal with circuit to determine if there's a current on on the branch or not, I'm using analogy to determine if there's a voltage on the branch if there's a current, but what's confusing me that It takes for me much time to determine if there's current or not.

for example lets assume I have GND connected serial with resistor and through the resistor there's no current, then we have the same voltage .. but why!? it looks simply yeah .. but I do equations to prove why voltage is the same.... what's I'm asking about .. is there any more senseable analogy to take it in advance for determining if there's the same "voltage" or not on the branch?! for instance by that analogy that you give me can immediately determine if I still have the same voltage or not on the device! -- it would be appreciated if you implicitly explain the concept of voltage and current, relations between them in aspect of senseable real life analogy --

thanks alot.
