A non-qualified annuity can be established either as an immediate or a deferred annuity. A large one-time payment, otherwise known as a single premium, is likely to be used to fund a non-qualified immediate annuity.
In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule. If charge is transferred to an insulator at a given location, the excess charge will remain at the initial location of charging.
The dielectric constant is a number without dimensions. The term insulator is generally used to indicate electrical obstruction while the term dielectric is used to indicate the energy storing capacity of the material (by means of polarization).
