Question:
A parallel RLC circuit, which is driven by a variable frequency 10-A source, has the following parameters:
R=500\Omega
L=0.5mH
C=20\muF
Find the resonant frequency, the Q, the average power dissipated at resonant frequency, the BW, and the average power dissipated at the half-power frequencies.
Answer:
Q, \omega_0, and BW are all straightfoward calculations.
Q = 100 [/itex]<br /> BW = 100 \frac{rad}{sec}<br /> \omega_0 = 10000\frac{rad}{sec}<br /> <br /> The half power frequencies are:<br /> \omega_{hi} = 1005.01<br /> \omega_{lo} = 995.01 [/itex]<br /> <br /> I don&#039;t understand how to calculate the average power dissapated at resonant frequency, OR at the half power frequencies. If someone could give me a push in the right direction, that would be swell <img src="https://www.physicsforums.com/styles/physicsforums/xenforo/smilies/oldschool/redface.gif" class="smilie" loading="lazy" alt=":redface:" title="Red Face :redface:" data-shortname=":redface:" />
