A pair of parallel conducting plates have potentials of -17 V and 55 V,respectively.How much work needs to be done on an electron in order to move it from the 55 V to the -17 V plate?

Question

Quizplus · Accepted Answer

The work done on an electron is given by the change in electric potential energy, which is the charge of the electron multiplied by the potential difference. The potential difference is (-17 V) - (55 V) = -72 V. The work done is (-1.6 x 10^-19 C) * (-72 V) = 1.2 x 10^-17 J.
