Physics - Modern Physics Question with Solution | TestHub

Total energy of electron is stated as $E=-\frac{Z^{2}m{e}^4}{8{\left(nh{\epsilon }_0\right)}^2}$, potential energy $P=-\frac{Z^{2}m{e}^4}{4{\left(nh{\epsilon }_0\right)}^2}$ and kinetic energy is given by $K=\frac{Z^{2}m{e}^4}{8{\left(nh{\epsilon }_0\right)}^2}$.

So, as electron makes transition to higher level, total energy and potential energy increases due to the negative sign while the kinetic energy of electron decreases.
