The electric potential energy stored in the capacitor of a defibrillator is 70 3, and the t capacitance is 135 uF. What is the potential difference that exists across the capacitor plates? Additional Materials D Section 19 5
Explain why capacitance ?C depends neither on the stored charge ?q nor on the potential difference ?V between the plates of a capacitor. Capacitance is determined only by the physical properties of the capacitor. The stored charge ?q and the potential difference ?V are independent of the size and shape of the capacitor. The net charge on a capacitor is zero, and therefore the potential difference ?V cancels. The stored charge ?q is inversely proportional to the potential difference ?....

Chapter 28, Problem 009 Your answer is partially correct. Try again. In the figure, an electron accelerated from rest through potential difference Vi=1.40 kV enters the gap between two parallel plates having separation d = 28.8 mm and potential difference Vz= 181 V. The lower plate is at the lower potential. Neglect fringing and assume that the electron's velocity vector is perpendicular to the electric field vector between the plates.
