Dielectrics
Dielectrics are insulating (non-conducting) materials that can produce electric effect without conduction. Movement of free charges is not possible in a dielectric, so they behave differently.
When a dielectric material is kept in an electric field, then the external field induces dipole moment. Due to which, net charges on the surface of the dielectric appears.
The SI unit of dielectric strength is
Options:
(a) `Vm^(-1)`
(b) `Vm`
(c) `mV^(-1)`
(d) `m^2V`
