An oscillating voltage of high frequency is applied to a load by means of copper wire of radius 1 mm. Given that the skin depth is 6.6x10^(-5) m for this frequency, what is the high-frequency resistance per unit length of the wire in terms of its direct current resistance per unit length?

Solution:
An oscillating voltage of high frequency is applied to a load by means of copper
