Question
You are given a RL circuit with the resistor in series with the inductor. If the frequency ? of the input sinusoid increase, what happen the magnitude and phase of the impedance? EXPLAIN!!!!!!!
Magnitude decreases and phase increases.
Magnitude increases and phase decreases.
Both magnitude and phase increase.
Both magnitude and phase decrease.
a.Magnitude decreases and phase increases.
b.Magnitude increases and phase decreases.
c.Both magnitude and phase increase.
d.Both magnitude and phase decrease.
Explanation / Answer
Magnitude = Sqrt(R^2+(wL)^2)
Phase = ATan (wL/ R)
As W increases, both magnitude and phase increases as both are proportional to w.
Option (C) is CORRECT
