Final answer:
The work done in moving the charge of 2C across two points with a potential difference of 12 volts is 24 J.
Step-by-step explanation:
To find the work done in moving the charge across two points, we multiply the charge by the potential difference between the points. In this case, the charge is 2C and the potential difference is 12 volts. So the work done is (2C)(12V) = 24 J. Therefore, the correct answer is C. 24 J.
