Homework Statement
Given an electric potential of Vo*sin(wt). This is applied to a parallel plate capacitor of area S, separation d and capacitance C. The questions are
a) What is charge Q on the plates?
b) Find the electric displacement current
c) Calculate the current in the wire.
Homework Equations
a) Q=CV
b) I=(epsilon)*d(phi)/dt
c) i=dQ/dt
The Attempt at a Solution
for part a, i got Q=CV=C*Vo*sin(wt)
for part b, i got I=(epsilon)*w*cos(wt)
for part c, i got i=C*w*cos(wt)
is this right, because i have a feeling that this is a little too easy of an answer.
why does the displacement current differ from the current in the wire?
