Answer:
The change in electric potential energy of the electron = 1.92 × 10^-18 J
Explanation:
Change on an electron q = -1.6 × 10^-19 C
Potential Difference ΔV = 12V
Change in ELectric Potential Energy
ΔPE = qΔV
= -1.6 × 10^-19 × 12
= 19.2 × 10^-19 J
= 1.92 × 10^-18 J
Therefore, the change in electric potential energy = 1.92 × 10^-18 J
Hope this answer is helpful.
