Questions about parallel plate size...
Hi everyone, new member here and I apologize in advance if my questions seem somewhat amateur.
Recently I've started learning about capacitors, electrostatics and electric theory in general. I guess I'm having trouble trying to wrap my head around the actual area (size) of the plates of a parallel capacitor. For instance...if I want to size a capacitor that has the charge of 1kwh...(3,600,000 joules), at 50 kv, the equations say I would need a cap size around .00288 farads.
When I try to calculate the area of the plates for a .00288 cap with .5 meter separation, a dielectric permittivity of 3...I get a plate area size of .00048 meter square.
This seems like an awfully small plate size to hold that amount of energy.
I guess I'm just looking for some validation to my answers, and if not maybe someone could point me in the right direction. Thanks for your replies in advance.
