Question 432: AC fundamentals

Question

If Z$_1$ and Z$_2$ are the impedances of the given circuits (a) and (b) as shown in figures, then choose the correct option

Accepted Answer

$\begin{aligned} & Z_1=\sqrt{X_L^2+R^2} \quad \quad X_L=O 	ext { (D.C. circuit) } \\ & Z_1=10 \Omega \\ & Z_2=\sqrt{X_C^2+R^2} \\ & X_C=\frac{1}{2 \pi 	imes 50 	imes \frac{10^3}{\pi} 	imes 10^{-6}}=10 \Omega \\ & Z_2=\sqrt{(10)^2+(10)^2} \\ & =10 \sqrt{2} \\ & Z_1 < Z_2\end{aligned}$

Answer

Z$_1$ < Z$_2$

Answer

Z$_1$ + Z$_2$ = 20 $\Omega$

Answer

Z$_1$ = Z$_2$

Answer

Z$_1$ > Z$_2$
