Based on the given Nyquist plot, answer the following questions1. Plots A, B, and C represent three different types of capacitors: electrical double layer capacitors, pseudocapacitors & electrostatic capacitors (name not in order). Tell which plot represents which capacitor.2. Draw three equivalent circuits that would best model three plots.3. Explain why plots B and C have an inclined 45° line, but not A.4. Why is there a semicircle in plot C?

The electric field strength between the plates of a simple air capacitor is equal to the voltage across the plates divided by the distance between them. When a kV voltage of 129. V is put across the plates of such a capacitor an electric field strength of 3.7- is measured. cm Write an equation that will let you calculate the distance d between the plates. Your equation should contain only symbols. Be sure you define each symbol. Your equation: d = Definitions of your symbols: kV = 3.7 cm = 129. V 00 X E Δ

Hi I'm given the diameter of the sphere is 25cm. An electric pen brought near this sphere causes a voltage of 5000 V. The distance between the sphere and the pen is 14cm. The pen itself is measured at 25cm.  they want to know what is the charge on the sphere?  Please break it down so I can understand. The last answer had the wrong diameter calculated into the problem and was missing what formulas they used for each problem and how they solved it in steps.
