A parallel plate capacitor with a capacitance of 0.86 F with a has plate area A and are separated by a distance d. It is charged up to 11 V. The capacitor is now disconnected from the battery. If the area of the plates increases by a factor of 3 and the separation decreases by a factor of 10, fınd the new charge on the capacitor in Coulombs.

A capacitor with plate area 0.0440 m2and plate separation85.0 mm is to be charged to 12.0 V and store 7.50 mJ of energy.What should be the dielectric constant of the material betweenthe plates?

An air filled capacitor C= 10uF is connected to a 15V battery. The capacitor is disconnected from the battery and the distance between the plates is doubled. What is the energy stored in the capacitor now?

Shown in the figure below is a capacitor. Each plate has an area of A = 3.45e-02 m² and has a gap d = 6.7e-04 meters. At the first moment, the capacitor is empty. At the second moment is it partly filled with a dielectric of constant K = 2.57. The thickness of the dielectric layer is a = 2.01e-04 meters leaving a free space of b = 4.69e-04 meters. d Empty Capacitor Area = A a b Partly Filled Capacitor Write the FORMULA for the capacitance of the empty capacitor. Determine the capacitance of the empty capacitor Cempty = Determine the formula for the partly filled capacitor Cfilled = Determine the value of the partly filled capacitor Cfilled = & A d When you partly fill the capacitor, which of these best describes the new configuration: O Both series and parallel O Neither series nor parallel Series O Parallel dielectric constant K Farads Farads NOTE: Decide whether the partly filled capacitor acts like parallel or series by following the charge: • If the charge splits between the caps,…
