Imagine that two parallel plates are charged to achieve a voltage difference Vo between the plates. They have area A and spacing d. The plates are then electrically isolated so that no charge can be added or taken away. A good conductor of thickness d/2 is placed in between the two plates, as shown. Does the voltage difference of the plates change? Why or why not? If yes, what is it in terms of the old voltage difference V? (Don’t forget ∆V=-integral of Edx.)

Imagine that two parallel plates are charged to achieve a voltage difference Vo between the plates. They have area A and spacing d. The plates are then electrically isolated so that no charge can be added or taken away. A good conductor of thickness d/2 is placed in between the two plates, as shown. How about the electrical stored energy, using the formula U = (1/2) QV? What was it before, and what is it now?
The space between two parallel conducting plates each having an area S is filled with an inhomogeneous ohmic medium whose conductivity varies linearly from a, at one plate (y = 0) to a, at the other plate (y= d). A d-c voltage }, is applied across the plates. Determine a) the total resistance between the plates, and b) the surface charge densities on the plites.
The diagram below depicts a cross section of coaxial conductor with an inner wire of diameter di and an outer conducting sheath of inside diameter do, and some material placed in the space between the two wires. Suppose that you have a coaxial wire with di=1.3 mm and do=7.55 mm, and we put mylar (κ=3.1) in the space between the two wires. If there is a potential of 1 kV between the wires, how much energy is stored in a 10 m piece of cable? For my answer I got 5.32 J which was wrong.
Consider following circuit with R1 = 62 Ω, R2 = 11 Ω, R3 = 62 / 10 Ω, R4 = 11/10 Ω and and ξ=11 V i. Cross sections through two long conductors of the same length and material, with square crosssections of edge lengths are shown below. Conductor Y fits snugly within conductor X, Rank theresistance of X and Y?

A capacitor with plates separated by distance dd is charged to a potential difference ΔVCΔVC. All wires and batteries are disconnected, then the two plates are pulled apart (with insulated handles) to a new separation of distance 2d2d. Does the potential difference ΔVCΔVC change as the separation increases? If so, by what factor? If not, why not? Match the words in the left column to the appropriate blanks in the sentences on the right.
A capacitive with two parallel plates of a capacity (C) was connected to a battery with a potential difference between its poles (15V), then an insulator was inserted between its two plates instead of air with a constant isolation (2), so the charge stored in any of its plates was (600MC) what is the amount? First: the capacitance of the expansion before the insulator. Second: The energy stored in the electric field between two plates of width before and after inserting the insulator.
