Question

When subjected to alternating stresses, an insulating material is characterised by complex dielectric constant &isin;&#39;r - j&isin; r . In such materials, the dielectric losses under alternating stress is proportional-A-&isin; rB-both &isin;&#39;r and &isin; rC-&isin;&#39;rD-(&isin; r)2-A-&isin; r

APTITUDE CRACK · Accepted Answer

The correct option is  A &isin; r The imaginary part of &isin;r gives rise to absorption of energy.
