The discussion clarifies the differences between disconnected and connected parallel plate capacitors, emphasizing that the potential difference (PD) across a connected capacitor is dictated by the voltage source, while a disconnected capacitor's PD is influenced by its instantaneous charge. The formula C(Q/V) = ke0A/d is central to understanding capacitance, where C represents capacitance, Q is charge, V is voltage, ke0 is the permittivity of free space, A is the area of the plates, and d is the distance between them. The capacitance remains constant regardless of the charge or voltage conditions.

The words alone don't have an unique message. What you (and we) would need is a circuit diagram of the two states you want to discuss.plindle said:I am having a hard time understanding the whole idea behind and the difference between disconnected vs connected parallel plate capacitor in terms of voltage and charge. How does this relate to the formula C(Q/V)=ke0A/d?
