AC Circuits

Question

In a series LCR circuit, operated with an ac of angular frequency $ω$ , the total impedance is

Moderate

A

${[R^{2} + {(Lω - Cω)}^{2}]}^{1 / 2}$
B

${[R^{2} + {(Lω - \frac{1}{Cω})}^{2}]}^{1 / 2}$
C

${[R^{2} + {(Lω - \frac{1}{Cω})}^{2}]}^{- 1 / 2}$
D

${[{(Rω)}^{2} + {(Lω - \frac{1}{Cω})}^{2}]}^{1 / 2}$

Solution

Impedance in a series LCR circuit is given by $Z = \sqrt{R^{2} + {(X_{L} - X_{C})}^{2}}$
