Im studying up on basic electronics theory because im still kind of new to all of this but now im stuck. I cant seem to get to the right answers for this practice problem:
Given that E=10V rms, f=15kHz, R=8.2k, L=40mH, and C=0.004uF;
Find the values of IR, IL, IC, IX, IS, ZT and the phase angle; the second letters of each should be read as subscripts.
I am getting the following;
IR=1.2mA, IL=2.7mA, IC=3.8mA, IX=1.1mA, IS=1.7mA and ZT=6046 Ohms
In getting those values i had to also get XL=3769.9 Ohms
XC=2652.6 Ohms and XT=8950.2 Ohms
Supposedly the answers should be as follows;
IR=1.22mA, IL=3.62mA, IC=2.76mA, IX=0.855mA, IS=1.49mA and ZT=6710 Ohms and the phase angle should be +35 degs.
Also since according to my calculations XL > XC, shouldnt the phase angle be negative because the source current will be leading the source voltage?
Thanks for any help.
