The expression for impedance of series R - L circuit is Z = ( R^2 + 4.π^2f^2L^2)^1 / 2

Here,

R = 20 Ω, L = 20 mH, V = 60 V and f = 100 Hz

Z = [20^2 + 4 × 3.14^2 × 100 ^2 × (20 × 10^ - 3)^2]^1 / 2 = 23.61 Ω

Therefore, electric current through the circuit i.e both through resistor and inductor will be 60 / 23.61 = 2.54 A.
