the two things that capacitance depends on?

95.)A sheet of insulating plastic material is inserted between the plates without otherwise disturbing the system What effect does this have on the capacitance? (A) It causes the capacitance to increase. (B) It causes the capacitance to decrease. (C) None; the capacitance does not change. (D) Nothing can be said about the effect without knowing the dielectric constant of the plastic. (E) Nothing can be said about the effect without knowing the thickness of the sheet.

What is the relationship of the capacitance to electric potential?

I need help seeing how this capacitor question is solved.

Why is the charge on capacitors always equal and opposite?

A simple adjustable parallel-plates capacitor is shown below. The plates have a radius of 8.0 cm and they are separated by a gap of 0.50 cm with nothing in between them. (a) Calculate the capacitance of this capacitor. (b) Calculate the charge stored when a battery of 9 V is connected to the capacitor. (c) Calculate the energy stored in the capacitor. (d) While the battery is still connected to the capacitor, a 0.50 cm-thick piece of wood (dielectric constant ? = 4.0) is inserted into the gap between the plates. Describe and explain what would happen to the capacitor’s voltage, to the capacitance, and to the stored charge.

Suppose one of the plates of a parallel-plate capacitor was moved so that the area of overlap was reduced by half, but they are still parallel. How would this affect the capacitance?

How would the capacitance of a parallel capacitor change if a dielectric was placed between the plates?

If you want to store 35 J of energy in a capacitor charged to 24 V , how do you determine the required capacitance?
