How much work is needed to carry an electron from the positive terminal to the negative terminal of a 9.0-V battery.(e = 1.60 × 10^-19C ,m_electron = 9.11 × 10^-31 kg)

Question

Quizplus · Accepted Answer

The work done to carry an electron from the positive to negative terminal of a battery is equal to the potential difference between the terminals, multiplied by the charge of the electron. Therefore, W = qV = (1.60 × 10⁻¹⁹ C)(9.0 V) = 14.4 × 10⁻¹⁹ J, which is option D. We don't need to use the mass of the electron for this calculation.
