Ferrites have - Materials and Components

Electronics and Communication Engineering (ECE) : Materials and Components - Quiz(MCQ)

Ferrites have

low eddy current loss

low resistivity

a low copper loss

higher specific gravity compared to iron

Correct Answer : Option (A) : low eddy current loss

Explanation : Resistivity of ferrites is very high as compared to that of iron. Hence eddy curretns are much less.
