25.
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 proportional
"r
both ∈'r and ∈"r
'r
(∈"r)2
Answer: Option
Explanation:

The imaginary part of ∈r gives rise to absorption of energy.
