Question
Point A is at a potential of -200V, point B is at a potential of -1700V and point C is at a potential of +950V. An electron is released from rest at point A. To which point is it likely to move?
Expert Solution
Step 1
We know that current flow always from higher potential to lower potential . so electron flow from lower potential to higher potential means negative terminal to positive terminal. if there are many points are given of different voltage then electron move between which terminal where potential difference is more.
VA=-200V , VB=-1700V , VC=+950V
work done =1/2 mv2 = potential differencecharge
