GATE 2020 1. )Skin depths in homogeneous media of resistivity  ρ 1  and  ρ 2  are 100 m and 200 m respectively at 1000Hz frequency. The ratio of  ρ 1 / ρ 2  will be...... Ans . Since skin depths are given as 100m and 200 m respectively           so using the  formula,                           skin depth (d) =503  √(ρ/f) , where  ρ- resistivity                                                                                            f- frequency        d1=503 √(ρ1/1000)        d2=503 √(ρ2/1000)                    n...
