look oppositely charge is brought close to a charged plate to decrease its potential and inturn increase capacitance.
the plate as such also has capacitance , i mean isolated .

so if u bring plate with same charge density then it creases potential but decreases capacitance but still its gotta be a finite value.

look its not necessary that the charges on the opposite plate is by the process of induction u can allways have a system like this what u say is right , that u have to charge both plates , given this system can it have a finite value of capacitance ???

u say it wud decrease , agreed , but does it have capacitance ???????

what i read in many books is that opposite and equal charges are taken to decrease the field thats all a single conductor has capacitance . now the book doesnt mention if like charged cap. can have capacitance

IN PARALLEL PLATE CAPACITORS CAN A SYSTEM OF TWO PARALLEL PLATES OF EQUAL AREA , SAME CHARGE DENSITIES HAVE CAPACITANCE ?? 


 


    |+             +|                     E inside = 0


    |+             +|                     dv/dr =  0 


    |+             +|                    v= constant


    |+             +|                    hence potential is nonzero 


    |+             +|                   so c =q/v which is a finite value ????

pretty close call but i wud suggest u can hav an effect similar to hyperconjugation acting here , making nh3+-nh3+ have a partial d.bond charecter so shorter bond length now further i say this coz N and C have comparable sizes

no u shudnt segregate physical and organic and also inorganic for example the reaction mechanisms are many time reinforced by thermodynamic , kinetics etc which come under physical chem . now a reagent used may be inorganic so definitely u even study reagents .



all the three branches go hand in hand .


 


moreover many carbon compounds are inorganic look at co2 .


 


at the same time physical chem. deals with carbon which is also a physical element u see . so there are inter linkages between all these fields but for our convineance what ever is told to u in the above threads is correct.

ITS GIVEN THAT COMPOUND2 IS MORE STABLE THAN ONE .


STABILISING FACTORS IN COMPOUND TWO INCLUDE HYPERCONJUGATION BY 4 ALPHA HYDROGENS


AND THE DOUBLE BOND SO FORMED IS IN CONJUGATION WITH C=C SO RESONANCE .


IN COMPOUND ONE THERE ARE SIX ALPHA HYDROGENS PLUS THE DOUBLE BOND IS IN CONJUGATION WITH C=O MAKING RESONANCE POSSIBLE AND INCREASING CLOUD DENSITY AROUND O SO ISNT COMPOUND 1 MORE STABLE THAN 2  ??

LASTLY,  A COMPOUND HAVING HIGHER DIPOLE MOMMENT IS MORE STABLE OR THAT WITH NO DIPOLE MOMMENT IS STABLE . I WAS UNDER THE IMPRESSION THAT IF DIPOLE MOMMENT EXISTS THEN MOLECULES HAVE DIPOLE DIPOLE INTERACTIONS WHICH ACTUALLY STABILISES THE SYSTEM . BUT I SEE THAT MY TEACHERS SAY TRANS IS MORE STABLE ???????????

kirchoff laws aplly to both capacitors as well as resistors right so is there any difference in its application to resistors / capacitors ??


havent read it yet that's why im asking .
