Do electrons tend to go to regions of low potential or high potential? A test charge \[{{q}_{0}}\] is moved without acceleration from point A to B along the path \[A\to C\to B\] as shown in figure. Calculate the potential difference between A and B. Test charge moving without acceleration            

Answer:

As electrons are negatively charged, they have tendency to go to regions of high potential. As clear from the graph, For        \[A\to B\to C\] As         \[E=\frac{dV}{dr}=\frac{-({{V}_{A}}-{{V}_{B}})}{d}=\frac{{{V}_{A}}-{{V}_{b}}}{d}\] \[\therefore \]      \[{{V}_{A}}-{{V}_{B}}=ED\]
