Question

Part A) Compute the impedance of a series R-L-C circuit at angular frequencies of ?1= 1000rad/s , ?2= 800rad/s and ?3= 515rad/s . Take R = 245? ,  L = 0.905H and C = 1.70?F .

Answer: Z1,Z2,Z3 = __________

Part B) Describe how the current amplitude varies as the angular frequency of the source is slowly reduced from 1000rad/s to 515rad/s .

Describe how the current amplitude varies as the angular frequency of the source is slowly reduced from 1000 rad/sec to 515 rad/sec

Part C)

What is the phase angle of the source voltage with respect to the current when ? = 1000 rad/s?

Amplitude is always constant. Amplitude decreases. Amplitude increases. First amplitude increases next it decreases. First amplitude decreases next it increases.

Explanation / Answer

First amplitude increases next it decreases.
