The average value of electric energy density in an Electromagnetic Waves is ($E_0$ is peak value ) |
$\frac{1}{2}ε_0E^2_0$ $\frac{E^2_0}{2ε_0}$ $ε_0E^2_0$ $\frac{1}{4}ε_0E^2_0$ |
$\frac{1}{4}ε_0E^2_0$ |
Electric energy density $u_e =\frac{1}{2}ε_0E^2_{rms}$ $E_{rms}=\frac{E_0}{\sqrt{2}}$ $u_e= \frac{1}{4}ε_0E^2_0$ |
