In a series L-C-R ac circuit driven at angular frequency 100 rad/s, the component values can be read from the figure. Determine the inductance of the coil and the capacitance of the capacitor.
- 0.8 H and 150 microF
- 0.8 H and 250 microF
- 1.33 H and 250 microF
- 1.33 H and 150 microF
Correct answer: 0.8 H and 250 microF
Solution
Reading the reactances from the figure and applying X_L = omega L and X_C = 1/(omega C) at omega = 100 rad/s yields L = 0.8 H and C = 250 microF for the standard version of this problem. (Exact numbers depend on the figure, which is not fully reproduced here.)
