Its equivalent, it's a conductor of length zero

http://hyperphysics.phy-astr.gsu.edu/hbase/electric/pplate.html And then you use the equation for capacitor in series 1/Ct=1/C1+1/C2

yes, i got confused, capacity is higher. and dielectric strength is irrelevant for low fields. what's relevant is dielectric constant. so, if dielectric constant of k is greater than the air, the capacitance of 2 will be greater.

that's both excellent answers! I'm reading about it now. I'm really grateful.

yes, those equations are wrong. the correct equations are those that I gave you. it is easy to do it yourself, just derive with respect to time and rember that sine and cosine are between 1 and -1. it is crucial to understand this that the maximum velocity or acceleration can't involve time

look, max velocity is $\omega xmax$. max acceleration is $\omega^2 xmax$. you shouldn't have any "time" involved.

the dielectric generates an opposing electric field. as a consecquence, electric field is lesser than with vacuum, which is the best dielectric. equivalently, the capacitance of a filledcapacitor is lesser than the one with vacuum. the word in spanish is "apantallar", i don't remember the word...

i don't think those equations of max velpcity have any sense. if they are maximum, why would tgey depend on time??

my question is this: you know than in feynman path integra, you integrate eiS/hbar along all the fields. you also know that S is real and that it is the integral of local functions (fields and derivatives of fields). you also know that path integral generates an unitary and local...
