Answer
a. $428\Omega$
b. $2.57\times10^{-2}\Omega$
Work Step by Step
Find the reactance of the capacitor using equation 21–12b, $X_C=\frac{1}{2 \pi f C}$.
a. $X_C=\frac{1}{2 \pi f C}=\frac{1}{2 \pi (60.0Hz) (6.20\times10^{-6}F)}=428\Omega$
b. $X_C=\frac{1}{2 \pi f C}=\frac{1}{2 \pi (1.00\times10^6Hz) (6.20\times10^{-6}F)}=2.57\times10^{-2}\Omega$
