My sweet padlet by mohammed shamshuddin https://padlet.com/shamshuddin2424/vyret6c1awinrtur Made with panache en-us 2021-05-04 05:15:46 UTC 2023-03-12 00:18:33 UTC hello@padlet.com Difference in the behavior of a conductor and di-electric in an external electric field https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488246509 In an electric field, in a conductor, the charge distribution in the conductor re-adjusts itself so that the net electric field within the conductor becomes zero, while in a di-electric, the external electric field induces a net dipole moment. The electric field, due to this induced dipole moment, opposes, but does not cancel the external electric field.]]> 2021-05-04 05:18:22 UTC https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488246509 Q2)What are di-electrics? https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488247566 Dielectrics are non-conducting substances having a very minute number of charge carriers .]]> 2021-05-04 05:18:59 UTC https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488247566 What are polar and non polar molecules? give examples https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488253057 When multiple atoms are bonded to each other, a molecule is formed. 
These bonds can either be polar when the electrons in the molecule are shared unequally or non-polar when the electrons are shared equally.
Eg- HCL (polar molecules)
       O2(non polar molecules)

net dipole moment is in the direction of electric field,i.e.,the dielectric is polarised.

And unlike ideal conductors where there are a lot of free electrons to completely nullify the effect of applied external fields .

Electric susceptibility is a constant that indicates the extent of polarization of a dielectric material in an electric field.]]> 2021-05-04 08:07:59 UTC https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488657816 shamshuddin2424 https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488658744 blue arrow--external electric field
green arrow--dipole 
 it is clearly evident that both the fields are opposing and hence cancel each other.thus net field magnitude decreases]]> 2021-05-04 08:08:19 UTC https://padlet.com/shamshuddin2424/vyret6c1awinrtur/wish/1488658744
