When AC flows in the conductor the current is non-uniformly distributed over the whole cross-section of the conductor, due to which outer filaments of the conductor carry more current then the filaments closer to the centre. This results in a higher resistance to AC than to DC and is known as the __________.
1
surrogacy effect
2
skin effect
3
spirality effect
4
proximity effect
