Question
I have a lot of trouble understanding batteries. Our textbooks are our university addtion so it's taught rather weird compared to other schools. please help me with as many parts as you can! or even giving me a general information that can help me answer these problems! Thank you!!
Suppose you use wires to connect 2 very very large conducting plates to opposite poles of a battery. In chemistry you learned that the battery pushes one electron after another onto the wire on the right and takes one electron after another from the other wire. The battery can "push" with a voltage difference of epsilon battery middot Knowing that like charges repel each other, decide how the extra electrons on one side (and the extra positive charges on the other side) arrange themselves on the (tiny) wires and the (gigantic) plates. After the battery has worked for a while, there are a lot of extra electrons on the plate on the right(lets call this total electrical charge -q) and a lot of extra positive charge on the plate on the left(lets call this total electrical charge q). How do these extra charges affect the batteries ability to push even more charge onto the plates? Will there come a time when the battery has pushed all the charge it can onto the plates? While the battery is "charging up" the plates, is there a current flowing in the wires? We usually define the capacitance, C, of a pair of conductors (like these two plates) to be the ratio of the total charge, Q, that is on the positive conducting plate (with -Q on the negative plate) and the voltage difference, Delta V, between the plates. That is, C = Q/Delta V. Given your answers to the other parts of this question, why is that a reasonable definition of the capacitance of this capacitor?Explanation / Answer
