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. Homework Equations Kirchoff's voltage law The Attempt at a Solution 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...
