Thank u I'm kinda satisfied (about the last reply ,I was on a rush ...) . I hoped for Newton's first law to explain the flow of current when delta V=0 (in ideal wire).

Does I(current) also equal to zero in case it is shortened by wire? If Yes , how do we explain the existence of current in any wire (that of course will have a delta V = 0 because a wire has a resistence equal to 0 ohm ) ?

Thank you for the fast replies . I read what u said quickly . I will read them more carefully when i have more time . Meanwhile i don't want the thread to die . Bare with me please : if we take Winstone circuit without galvonemeter/ammeter in the middle . (Just wire)And caculate the current...

Homework Statement Wheatstone bridge. Homework Equations i Why the voltage across whetstone's bridge isn't always zero ? according to ohm's law . It must be zero (V=I*R, R=0) =>V=0 across the bridge . The Attempt at a Solution I think I'm missing something . the following sentence isn't...
