Use our Skin Depth Calculator to quickly determine the effective depth of AC current penetration in a conductor. Understand how frequency, resistivity, and permeability impact current distribution, crucial for high-frequency circuit design and electrical engineering applications.
Formula:
The Skin Depth (δ) is calculated using the formula:
δ = √(ρ / (π × f × μ))
Where:
- δ = Skin Depth (meters)
- ρ = Resistivity of the conductor (Ohm-meters, Ω·m)
- f = Frequency of the AC current (Hertz, Hz)
- μ = Absolute Magnetic Permeability of the conductor (Henry/meter, H/m)
Note: Absolute permeability (μ) = Relative Permeability (μr) × Permeability of Free Space (μ0), where μ0 ≈ 4π × 10-7 H/m.
