In Ac (Alternating Current) Circuits, the Relationship Between the Impedance $\theta$

question 1

Multiple Choice

In ac (alternating current) circuits, the relationship between the impedance Z (in ohms) , the resistance R (in ohms) , the phase angle $\theta$ , and the reactance X (in ohms) is shown by the right triangle in the illustration.
