distance between prallel plate capacitor is increased what happens to the charges on plates, potential difference across plates, energy stored in the capacitor
Answers
The formula for the capacitance of a parallel plate capacitor is
C=ϵAx, where ϵ is the permittivity of the medium between the plates, A is the overlapping area of the two plates and x is the uniform separation between the plates.
Capacitance, intuitively, is the ability of a pair of conductors separated by a dielectric to store electrostatic energy - or in other words, how much charge the conductors can store at a given voltage level. It is analogous to the capacity of a bucket being how much water it can hold.
Q=CV
Assuming that the capacitor is connected across a constant voltage source keeping V constant,
increasing the distance between the parallel plates will decrease C
at a constant V, an increase in C will decrease the charge Q that the conductors can hold.
