$begingroup$ Thank you for your answer. I understood that heat is liberated in the presence of resistance in the circuit. I learnt from your answer to one of the linked questions, that the process of pulling the plates when battery is connected, is similar to that of recharging the battery. This fact is also discussed in my textbook and it''s said …
capacitance
The capacitor only works right if we pretend that it''s some sort of wire. With wires, if we try to push in more charge than we remove, both ends of the wire immediately charge up to fantastic values of voltage, and this blocks any further current. A capacitor in electronics does the same thing. More: the engineer''s capacitor. Why …

Why Do Capacitors Fail? Capacitor failure modes and common …
As the barometric pressure decreases so does the terminal "arc-over" susceptibility increase. Non-hermetic capacitors can be affected by internal stresses due to pressure changes. This can be in the form of capacitance changes or dielectric arc-overs as well as low I.R. Heat transfer can be also affected by high altitude operation.
