A parallel-plate capacitor is constructed by filling the space between two square plates with a block of three dielectric materials, as shown in the figure below. You may assume that ℓ ≫ d. A parallel-plate capacitor is comprised of two square plates with sides of length ℓ and separation distance d. There are three dielectric materials in the space between the capacitor plates. A material with length ℓ⁄2, height d, and dielectric constant ?1 fills the left half of the space. A material with length ℓ⁄2, height d⁄2, and dielectric constant ?2 fills the top right quarter of the space.

Assume that the internal diameter of the Geiger– Mueller tube described is 2.50 cm and that the wire along the axis has a diameter of 0.200 mm. The dielectric strength of the gas between the central wire and the cylinder is 1.20 x 106 V/m. Use the result of that problem to calculate the maximum potential difference that can be applied between the wire and the cylinder before breakdown occurs in the gas.

A parallel plate capacitor has a charge Q, and a voltage difference AV. The gap is air-filled with an electric field E. 1. The capacitor is then disconnected from the circuit so that there is no path for the electrons to move from one plate to another. An insulator of dielectric constant *> 1 is then inserted to fill the entire gap. The electric field in the gap will cause the charges in the dielectric to separate slightly. This leaves an excess layer of negative charges on the top of the insulator and an excess layer of positive charges at the bottom surface of the insulator. This induced surface charge creates an induced electric field opposite the direction of the original electric field. a. The new net electric field is Ē' = Z₂ + Ēinduced. Which is true of E', the magnitude of the new net field? Choose one. E' = E, (the net electric field is the same as the original electric field) E' = E₁/x (the net electric field is smaller than the original field.) b. Which is true of the new…
