sir i have a question related polarisability ..a charge q is elasticaly bound with spring constant k.then what is the value of polarisability?
sir you did'nt explain pyroelectric and antiferroelectrical......

that is not in syllabus IN non-tech portion.. it is in tech portion syllabus(only for EE/EC)
VH=B.I/rho*w kaise aaya?

this equation you have to remember.. ther is no derivation in that.. jus try to balance the unit of both sides.. in that way you will remember that equation..
