Ya, thanks I think I figured it out. I tried to simplify the problem by leaving the switch out, but that let's you figure out the voltage.
What I didn't tell you was that the switch causes Vc to be 40V before and after 0.
Then, I just think that no current can flow through the capacitor...
Homework Statement
I am trying to understand how to get the voltages Va and Vc in the following circuit.
It is assumed the circuit has been like this for a very long time.

So I know that the capacitor acts...
Hi, I'm studying the wave nature of particles.
My book says that the de broglie wavelength of an electron is h / momentum, or h / (mv).
I also have that E = hf = momentum2/(2m) = 1/2 mv2.
I know that for a photon the frequency is speed of light / wavelength.
I'm wondering why the...
