what are the losses of capacitor??



what are the losses of capacitor??..

Answer / kedam.koteswar

the losses in ac capacitors. All dielectrics (except vacuum) have
two types of losses. One is a conduction loss, representing the &#64258;ow of actual charge through
the dielectric. The other is a dielectric loss due to movement or rotation of the atoms or
molecules in an alternating electric &#64257;eld. Dielectric losses in water are the reason for food and
drink getting hot in a microwave oven.
One way of describing dielectric losses is to consider the permittivity as a complex number
