When voltage applies on pure insulator, called dielectric. In insulator case power loss = v^2.2*fc.tan δ.

According to jouls 3rd low: when constant current flows through a conductor the heat is produced proportional to the time of flow of current.

H^T when I&R constant.
we know that t=1/f. So H^1/f, how?

According to joules law heat is equal to i^2 * R * T.

Then what is the relation between heat and frequency?
