Thank you. So in this "simple picture", are we neglecting current decay due to ion-ion collisions? And I guess electron-ion collisions are too effective to ignore.
q(Vf - Vi) is correct for the work done by the force opposing the electric force. If the work done by electric field was being considered, it would be q(Vi - Vf).
Hello PF,
This has been frustrating me for a while:
The plasma inside a tokamak is being heated by current induction, which accelerates the ions and electrons in specific directions, thus the velocity of ions increase. These ions collide with each other, eventually randomizing the motion. Now...
