why is current same in series connections of resistance and potential diff. in parralel connection of resistance

FOR PARRALLEL CONNECTION

the wire in a circuit is a conducting wire and we know that conductors r equipotential surfaces. so since the applied emf across all the resistors are same hence potential remains same across the resistors in parallel. it ud be better if u draw a circuit diagram and analyse it.

for series across the resistors charge flow per unit time is constant hence current remains same.

edison

As in series connection of resistance the path of electron is same and there is no distribution at junction thus total no. of electrons crossing a point at any point remains same that decides the current in the circuit.

But in parallel the no. of electrons divide themselves in sucha manner that continuity of chare and kirchoff's first law holds good. That is charge at the junction is conserved or incoming charge is equal to charge crossing the junction.

hhmm a better explanation.
