Explain the rationale of using a small WD to improve resolution ?

what is the average power for an 8.0-mF capacitor attached to a120-V ms 60-Hz source?

a) 240 W
b) 120 W
c) 85 W
d) 60 W
e) 0

A 100-W resistor, an 800-mH inductor and a 10.0-mF capacitor areconnected in series across a 60.0-Hz 120-V (peak) ac source. Theimpedance of this circuit is approximately

a. 107 W
b. 265 W
c. 100 W
d. 377 W
