Homework Statement A capacitor of capacitance 10 uF is raised to a potential difference of 150V. After disconnecting from the battery, it is connected to a capacitor of capacitance 5 uF. Find the energy of the system. Homework Equations Energy supposed to be equal in the first case and second...

My name is Rashad. Profession: Instructor ( Electrical department), BSRM Technical Training Center. I am currently studying Electrical and Electronic Engineering at institutes of Engineers Bangladesh.

Amazing! Thank you BvU... ☺

Yes. I saw it and to skip those lengthy calculation, I was to try applying Gauss's Law. But we can't right?

There was two question. 1. find electric field due to infinite charged plate. In the solution, Gauss's Law was applied. 2. Find electric field due to charged disk having radii R at a point on the axis. In this case, a lengthy calculation had made to find the field. So I thought why can't we use...

In case of disk having finite radii right?

Thank You. I studied and understood that the plane in the question was an infinite plane but in case of the disk it was defined by finite radii R. I tested the equation derived from such disk assuming R is infinity which gave me the same equation derived assuming infinite charged plate using...

We apply Gauss's law to find electric field at a point due to chaged plane or plate. But what's wrong when applying to circular disk which can also be considered as a plane?
