Final answer:
The work done in carrying an electron across a potential difference of 10V is -1.60 x 10^-18 J (joules).
Step-by-step explanation:
The work done in carrying an electron across a potential difference of 10V can be calculated using the formula:
Work = Charge x Potential Difference
The number of electrons lost flowing through a resistor when the voltage across the resistor is 10V and the resistance is 10 ohms would be 6.24 x electrons.
Since the charge of an electron is -1.60 x 10-19 C and the potential difference is 10V, we can plug in these values to calculate the work:
Work = (-1.60 x 10-19 C) x (10V) = -1.60 x 10-18 J
Therefore, the work done in carrying an electron across a potential difference of 10V is -1.60 x 10-18 J (joules).
