(c) Which assumptions are responsible?arrow_forward(a) What is the energy stored in the 10.0 F capacitor of a heart defibrillator charged to 9.00103 V ? (b) Find the amount of stored charge.arrow_forwardAccording to UE=12C(V)2 (Eq. 27.3), a greater capacitance means more energy is stored by the capacitor, but according to UE = Q2/2C (Eq. 27.2), a greater capacitance means less energy is stored. How can both of these equations be correct?arrow_forward
