In This post you will get answer of Q.
A 1.0 mH inductance, a 10 $mu F$ capacitance and a 5.0 ohm resistance are connected in series to an a.c. source. It is found that the inductor and the capacitor show equal reactances. The reactance should be nearest to
Solution:
$omega = (1/LC)^{1/2}$ and $X_L = omega L .$
Solution:
