| 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? |

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