1.1.6 Capacitors and inductors at DC The impedance of an inductor is $Z_L = j\omega L$, and the impedance of a capacitor is $Z_C = \frac{1}{j\omega C}$. For a circuit at can consider the frequency to be zero ($\omega = 0$). Please calculate these impedances at dc. $Z_L = $ $Z_C = $ An open circuit is a circuit that is disconnected, and a short circuit is a circuit where current passes un around a circuit element. Please memorize these terms, and consider whether $Z_L$ and $Z_C$ are open circuits circuits. At DC, which impedance is a short circuit? At DC, which impedance is an open circuit?
