Document Summary

A capacitor consists of 2 conductors that are close but i touching me another. " has the ability to store electrical charge , and thus electrical potential energy. A parallel - plate capacitor connected to a battery , and the circuit diagram used to describe it i o in:*::* " when a capacitor is connected to a battery with potential difference or voltage , change on its plates is proportional to v in a steady state situation : " unit of capacitance : the farad cf) if - capacitance of the capacitor. " for a parallel - plate capacitor as shown the field between the plates is : Integrating along a path between the tree plates gives the potential difference : F: ei . ( dx ) l - x ) " this means the capacitance b : c - eu = qatogtt. Capacitors are now made with capacitance of tf or more.

A parallel-plate capacitor with an air gap has capacitance C₀. It is connected to a battery with potential V₀ that gives it charge Q₀ and stored energy U₀. After the capacitor is disconnected from the battery, a dielectric with constant κ = 3 is inserted into the air gap, completely filling it. In terms of the initial values, find the new capacitance C, charge Q, potential V, and stored energy U.

This question has been asked before, but I don't believe theanswer was entirely correct. Really think about number 1 with B andhow e would be affected.

A parallel plate capacitor was connected to a DC Battery andCharged. The separation between the plates was then increased by afactor of two. Apply the following scenarios:

1.) Before the separation was Increased the Capacitor wasdisconnected from the battery.

2.) The Capacitor remained connected to theBattery while the separation was Increased.

For both scenarios show How the following quantitiesChanged..
a.) Capacitance?
b.) Charge on the Capacitor?
c.) Potential Difference between the Plates?
d.) Electric Field between the Plates?
e.) Energy Accumulated in the Capacitor..In particular has therebeen work done to move the platesand has there been energy drawn from the battery or did thebattery receive energy from the work done onseparating the plates?

My Homework problem has 4 parts to it and I can't figure out if I'mdoing it write because If I mess up I wont be able to do the otherparts.
