What is the Quantum Effect in ac conductivity?
Just go through the file.
Agree with Prof. Artur Sir's View.
Thanks all. Dear Braun Sir, please explain it.
Measurement of magnetoelectric current (density) seems to be very popular to investigate the magneto-electric response of multiferroics. It'll be grateful to know how it is measured and about the...

We often see two relation for calculation the dielectric permittivity: (1) E= C/C0 where E = dielectric permittivity, C = capacitnace and C0 is the geometric capacitance. (2) E =...

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
