Question 445: 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$$_2$$
