Question

Describe how the phase angle changes as you move from below resonance to above resonance Based on your results here and other textbook resources, what will happen if your frequency is much lower than resonance? What about much larger?

Answer 1

Answer:

Answer

Explanation:

In a LCR Circuit, the phase difference between voltage and current is usually summarized as;

tan∅ = XL- XC

               R

     =WL - 1/WC

            R

When w=0 ( i.e when it is very low)    tan∅ = ∞

                                                         or      ∅ = -90

When w=0 ( i.e when it is very large)    tan∅ =+ ∞

                                                         or         ∅ = +90
