what is skin effect?

2 Answers

Skin effect is cause due to high frequency in skin effect the current flows more at the surface of conductor than the centre of conductor. Skin effect causes resistance of conductor to increase and inductance of conductor to decrease at high frequency.

Skin effect is occurs in conductor due to high frequency...as the frequency increases the resistance of conductor increases...skin effect means the current flow through the skin of conductor....as the frequency increases the skin width decrease...means for dc current their will be no skin effect...I hope you understand basic concept of skin effect
