WebMar 5, 2024 · The potential difference across the plates is E d, so, as you increase the plate separation, so the potential difference across the plates in increased. The capacitance decreases from ϵ A / d1 to ϵ A / d 2 and the energy stored in the capacitor increases from A d 1 σ 2 2 ϵ to A d 2 σ 2 2 ϵ. WebIf the potential of the plate A is made negative, the photocurrent does not immediately drop to zero but flows in the same direction as for positive potential. This shows that the photo electrons are emitted from the plate C with finite velocity. If the negative or retarding potential is further increased, the photo current decreases and ... chirp yoga wheels
