## Main Question or Discussion Point

Problem:

Iv been trying to prove that the energy reisdes in the magnetic field in a good conductor and equally in both electric and magnetic for an insulator. My problem lies in the time averaging part of the problem...i cant seem to find out how they do it!

The time averaging formula used is:

For conductor:

<1/2 [tex]\epsilon[/tex] E[tex]^{2}[/tex]>/<1/2 [tex]\mu[/tex] H[tex]^{2}[/tex]>

is worked out to this:

[tex]\epsilon[/tex]E[tex]^{2}[/tex]/[tex]\mu[/tex] H[tex]^{2}[/tex]

The epsilons and mu's look like superscripts but there just multipled in!

any thoughts?
