  • Dielectric | physics | Britannica

    Dielectric, insulating material or a very poor conductor of electric current.When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material.Instead, electric polarization occurs. The positive charges within the dielectric are displaced minutely in the direction of

  • Electrical Resistance - Definition, Unit, Formula,

    When an electric current flows through a bulb or any conductor, the conductor offers some obstruction to the current and this obstruction is known as electrical resistance and is denoted by R. Every material has an electrical resistance and this is the reason why conductors give out heat when current passes through it. In the next few sections, let us study electrical resistance in detail.
