State the disadvantages of skin effect.

Last answer: Disadvantages of skin effect:- 1. Full cross section of conductor is not utilized, Therefore effective area of conductor reduces so its resistance increases. 2. Due to increase in resistance, copper ... increases (Since Voltage drop = IR ) 5. So voltage regulation becomes poor (increases)
