(a) Define volt, the unit of potential difference.
(b) Calculate the work done required to move an electron between two points A and B located at a potential difference of 100 V in an electric field.
Solution
(a)
1 Volt is the potential difference between two points in a current carrying
conductor when one Joule work is done to move a charge of 1Coulomb from
1J
one point to the other. / 1V = 1C
W
(b) V= Q
W=QxV
W = 1 6 10−19 100
W = 1 6 10−17 J
