Q1: When subjected to alternating stresses, an insulating material is characterised by complex dielectric constant ∈'r - j∈"r . In such materials, the dielectric losses under alternating stress is proportionalA
∈"r
B
both ∈'r and ∈"r
C
∈'r
D
(∈"r)2
ANS:A - ∈"r The imaginary part of ∈r gives rise to absorption of energy. |
