This is a quick one: Is there a way to tell how many linearly independent solutions there are to a differential equation? Like by its order? I have to solve a third order differential equation, and I am wondering how many possible linearly independent solutions there are. Three perhaps? Thanks!

Wow, thank you! This makes sense to me now. Thanks so much!

Okay, thanks! That makes sense. That just leaves me with one (kinda silly) question. So when measuring this effect in the lab, we were able to apply voltage across the anode and measuring the current through the anode. What is the difference between the anode current and the emission...

I have a question regarding Child's Law with thermionic emission. I understand that due to space-charge effects, that the emission current from a cathode reaches a saturation current at a certain temperature, explained mathematically by Richardson's Law. Utilizing an accelerating positive...
