I am new to Mathematica.
I am trying to figure out how to do the same thing in Mathematica as the image depicts done in Mathcad.
Declaring the variables with units I figured out.
U = Quantity[100, "Volts"]; f = Quantity[50, "Hz"]; R1 = Quantity[20, "Ohms"]; L1 = Quantity[0.005, "Henries"]; XL1 = UnitSimplify[2 π f L1]
I am stuck on how define Z1 with the angle.
