# A parallel-plate capacitor with capacitance C 0 stores charge of magnitude Q 0 on plates of area A 0 separated by distance d 0 . The potential difference across the plates is Δ V 0 . If the capacitor is attached to a battery and the charge is doubled to 2 Q 0 , what are the ratios (a) C new / C 0 and (b) ΔV new /Δ V 0 ? A second capacitor is identical to the first capacitor except the plate area is doubled to 2 A 0 . If given a charge of Q 0 , what are the ratios (c) C new / C 0 and (d) Δ V new /Δ V 0 ? A third capacitor is identical to the first capacitor, except the distance between the plates is doubled to 2 d 0 . If the third capacitor is then given a charge of Q 0 , what are the ratios (e) C new / C 0 and (f) Δ V new /Δ V 0 ?
