Suppose we have two parallel plates (each of area $A$) spaced with distance $d_1$ acting as a parallel-plate capacitor within a circuit. If the capacitor is connected to a power source with constant voltage $V_s$, positive charge will accumulate on the parallel plate connected to the positive terminal and negative charge will accumulate on the plate connected to the negative terminal. This will create an electrical potential difference between the two plates.
Does this process continue until the voltage $V_t$ between the plates is equal to $V_s$, and if not, how can we calculate the terminal voltage? Suppose we move the plates closer to distance $d_2$. Will the terminal voltage be identical to that of $d_1$?
