- Find the capacitance of the equivalent capacitor to the circuit of capacitors below between points A and B.Assume that each capacitor has a capacitance of C.An air-filled parallel-plate capacitor has capacitance Co. When it is connected to a battery with EMF Vo, it has charge Qo and stored energy Uo. The gap is then filled with a slab of material that has dielectric constant K. Vo Vo d A A KFor b of this question, I think it's using the wrong formula. The question itself specifically states that capacitors are discharging, so shouldn't you use the formula V=Vs(e^(-t/RC)) instead of the formula V=Vs(1-e^(-t/RC)), which is for charging capacitors? Please correct me and tell me why if I'm wrong. Thank you!
