How much work (as measured in joules) is required to push an electron through a region where the potential change is +73 V? Assume the electron moves from a region of low potential to a region of higher potential.
1 J
What is V*chargeonelelctron?
To calculate the work required to push an electron through a potential difference, we can use the formula:
Work (W) = Charge (q) * Potential Difference (V)
In this case, the charge of an electron is -1.6 x 10^-19 coulombs and the potential difference is +73 V. However, we need to take into account that the electron is moving from a region of low potential to a region of higher potential, which means the potential difference should be negative.
To convert the potential difference to a negative value, we simply change the sign of the potential difference:
Potential Difference (V) = -73 V
Now we can calculate the work:
Work (W) = Charge (q) * Potential Difference (V)
= -1.6 x 10^-19 C * -73 V
Multiplying these values together:
W = 1.168 x 10^-17 C * V
The unit for work is joules (J), so this answer is already in joules. Therefore, the work required to push the electron through a region with a potential change of +73 V is approximately 1 J.
