Question
Tell whether the ac resistance is higher than the dc or not.
Expert Solution
Step 1
The AC current follows the skin effect which means the current flows only from the outer side or the surface of the cable.
Whereas in dc current, the current gets distributed to all over the conductor. Therefore, the cross-sectional area for the ac will decrease.
