SUMMARY
An electron accelerated through a potential difference of 10 kV in a TV picture tube achieves a kinetic energy of 10,000 electron volts (eV). The conversion from Joules to electron volts is confirmed, with 1 eV equating to 1.6 x 10^-19 J. The calculated kinetic energy of 1.6 x 10^-15 J translates directly to 10 keV, affirming the accuracy of the conversion process.
