A capacitor is constructed out of two 1€ coins facing each other in air at a distance of 0.5mm and connected to a voltage source of Vs = 9V. Note: € is the symbol of the European currency as $ is the symbol of the US currency. The permittivity of vacuum is ε0 = 8.854-10-12 F m' The relative permittivity of distilled water is εr = 80. What is the formula to find the energy stored in the capacitor? W = CV-2 W = CV² ○ W = (CV)² W = CV-2 W = V² ○ W = (CV)-2 ○ W = CV2 ○ W = V-2
