a parallel plate capacitor has plates of dimensions 20cm by 20cm seperated by 2mm. The dielectric constant of the material between the plates is 5 and the plates are connected to a voltage source of 500V. calculate (a) the capacitance, (b) the charge on either plate, © the energy density, and(d) the total energy stored in the capacitor.

What have you done so far too try and solve the?

Why do you post this question?

because you don't know........

Because we help with homework, we don't do it for you.

Actually I didn't ask you sorry for the confusion. It was for OP.

So, you asked someone who posted a question in the homework help section why they posted that question.

I'm going to stick my neck out and suggest it's because it's a homework question, and they wanted help with it.

you don't get my point I was trying to know what the OP didn't understand and don't be silly everybody know why somebody posts in homework thread ,to get help.

Hey. Please, I'm sorry. I actually needed help, but have gotten one now. I have managed to produce the solution myself. thanks all.

Hi Mozart, glad you got it sorted.

Mozart, don't you know how to calculate capacitance of a capacitor it is the first lesson when you begin capacitor after definition.
