At a frequency of 60 Hz, the 160 millihenrys of inductance give us 60.319 Ω of inductive reactance. This reactance combines with the 60 Ω of resistance to form a total load impedance of 60 + j60.319 Ω, or 85.078 Ω ∠ 45.152 o.If we''re not concerned with phase angles (which we''re not at this point), we may calculate current in the circuit by taking the …
