Dept of ECE, National University of Singapore Chunxiang ZhuDielectric loss - ris static Dielectric constant (result of polarization under dc conditions). Under ac conditions, the Dielectric constant is different from the above as energy losses have to be taken into Thermal agitation tries to randomize the dipole orientations. Hence dipole moments cannot react instantaneously to changes in the applied field The absorption of electrical energy by a Dielectric material that is subjected to an alternating electric field is termed Dielectric In general, the Dielectric constant ris a complex number given bywhere, r is the real part and r is the imaginary of ECE, National University of Singapore Chunxiang ZhuDielectric loss - Consi
