How did you find PF?
Reddit
I came across this community in hopes of expanding my knowledge and satisfying my curiosity. So many unanswered questions. So many possibilities. So many potential outcomes.

How did you find PF?: Reddit

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 the electrons; will the conversion efficiency rise? If yes, how slow should they be? And by how much will the efficiency rise?
Welcome to PhysicsForums! :smile:

The New Member Introduction forum is only for brief introductions, not for technical questions. Please post your question in the Classical Physics forum, mark it with a "B" prefix (for Basic level discussion), and pleases include links to a couple of the sources you have been reading about your question. That will make it much easier to help you understand the issues.

Enjoy PF! :smile:

Thank you for your reply. Will definitely re-edit my New Member Introduction paragraph.
 
Hello everyone, I'm Cosmo. I'm an 18 years old student majoring in physics. I found this forum cause I was searching on Google if it's common for physics student to feel like they're in the wrong major in the first semester cause it feels like too much for me to learn the materials even the ones that are considered as "basic math" or "basic physics", I've initial fascination with the universe's mysteries and it disconnect with the reality of intense, foundational mathematics courses required...
