When to put positron or beta + decay in feynman diagram, & how does Lower R=higher PWatch
Question 6)c)ii) I thought there will be more energy released as some it will be lost (simply don't understand this question HELP !

For your first question, beta+ is the process of getting a positron and an electron-neutrino, and beta- is an electron and anti-electron-neutrino - so they aren't quite synonymous.
For the second part, do you get that the wire will be cooler so have lower resistance? Using P=(V^2)/R, if R goes down, P goes up. Does this help?
Let me know if you want it explained more
