27. An electron is accelerated from rest through a potential difference of 200. volts. What is the work done on the electron in electronvolts? 26. Calculate the potential difference across a 6-ohm resistor if 4 joules of work are required to move 2 coulombs of charge through the resistor. 23. How much energy is needed to move one electron through a potential difference of 1.0 x 102 volts? (1) 1.0 J (2) 1.0 x 102 J (3) 1.6 x 10-17 J (4) 1.6 X 10-19 j 24. In an electric field, 6.0 joules of work are done to move 2.0 coulombs of charge from point A to point B. Calculate the potential difference between points A and B.
