Consider a parallel-plate capacitor with plate's area A = 18.9 cm2 and separation between the plates d = 2.8 mm. What are the charge and energy stored on the capacitor if it is connected to a 70-Volt battery? The capacitor is filled with air. The charge, Q1 = C] Units . The energy, u1 = C] Units . If a dielectric material with K= 2.1 is inserted so that it fills the space between the plates (with the capacitor still connected to the same battery), what are the new changre and energy on the capacitor? The new charge, Q2 = C] Units . The new energy, U2 = C] Uni: \\/ Select an answer . V . ' . m/s Question Help. BMessageinstru- m/Shz 8 Submit Question nC kg m M no units required
