WebSep 12, 2024 · To find the charge q moved, we solve the equation ΔU = qΔV: q = ΔU ΔV. Entering the values for ΔU and ΔV, we get q = − 30.0J + 12.0V = − 30.0J + 12.0J / C = − 2.50C. The number of electrons ne is the total charge divided by the charge per electron. That is, ne = − 2.50C − 1.60 × 10 − 19C / e − = 1.56 × 1019electrons.
