State the disadvantages of skin effect.

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 losses increases (Since copper losses = I^{2}R )

3. So transmission efficiency reduces.

4. Due to increase in resistance, Voltage drop increases (Since Voltage drop = IR )

5. So voltage regulation becomes poor (increases)
