If an electron is accelerated from rest through a potential difference of 25,000 volts in a color television picture tube, its kinetic energy will be

Question

Quizplus · Accepted Answer

The kinetic energy gained by an electron accelerated through a potential difference V is given by the equation KE = eV, where e is the charge of the electron (1.6 × 10^-19 C). For V = 25,000 volts, KE = 1.6 × 10^-19 C × 25,000 V = 4.0 × 10^-15 J.
