In a series $L CR$ circuit the frequency of a $10 V$ a.c. voltage source is adjusted in such a fashion that the reactance of the inductor measures $15Ω$ and that of the capacitor $11Ω$ . If $R = 3Ω$ , the potential difference across the series combination of $L$ and $C$ will be:

Options:

Answer:

Solution:

$X_{L} = 15Ω; X_{C} = 11Ω; R = 3Ω$ $Impedance, Z = R^{2} + (X_{L} - X_{C})^{2} = 9 + 16 = 5Ω$
