Undergrad Question regarding Electrical Resistivity of metal vapors
Thank you for your response. It is very helpful. I should have been more specific and called it plasma. You're right. When i said "tube" I meant that the tube would be made of material that is not electrically conductive. But considering the difficulty of keeping the gas in a conductive plasma...- andrew_bak

Undergrad Question regarding Electrical Resistivity of metal vapors
You are right. I should have been more specific. Let's assume that under the proper conditions (Pressure, ionizing radiation, etc..) we have conduction. What is the highest electrical conductivity ever recoded? for both potassium and casesium vapor?- andrew_bak

Undergrad Question regarding Electrical Resistivity of metal vapors
What is the electrical resistivity of Caesium vapor? What is the electrical resistivity of Potassium vapor? Sorry there are no support material or reference links for this. Just a question. The unit must be in Ohm-meter.- andrew_bak

High School Question regarding Beta-voltaic cells and their efficiency
I see. So basically, by using a "sensitive" material would improve efficiency and altering the speed of the incident electrons has no effect? Thank you.- andrew_bak

High School Question regarding Beta-voltaic cells and their efficiency
I googled through dozens of posts to find that claim. I don't recall exactly which one. It would be difficult for me to find the corresponding link.- andrew_bak

High School Question regarding Beta-voltaic cells and their efficiency
Why are beta voltaic cells so inefficient? Is it because the incident electrons are incredibly fast? According to a research, the incident electrons that get absorbed by the voltaic material are so fast that most of their energy is wasted as phonon and sonic energy. If we substantially slow down...- andrew_bak
