Answer / prakash g.r.

It is a approx. method (ie) 2 A/mm2 for copper in air.

Answer / raju

resistance r=l/a, length/area of cross section then we get the
resistence value...so using ohms law we can solve the problem

how can we avoid magnetostriction in transformer?describe the suitable methods.
