Skin effect causes the currents to flow more on the surface layers of conductor and less on the middle. This increases efective resistance felt.
But does this effect also reduce the current that will flow (compared to scenario at same voltage amplitude, but now DC with the circuit that never had any reaktance components)?
I am asking this because in induction heating if you increase the frequency, the skin depth decreases which increases the resistance.
Losses are calculated by P=I^2*R, which means that losses would increase if we increase the frequency because resistance increased. But wouldn't increase in resistance because of skin effect reduce the currents, so the overal losses would now be smaller?
I am also aware of the effect that increasing frequency increases emf. But if we ignore the increase in emf, would the current and so losses increase or decrease, or would the current stay the same?
