Circuit Types DC Circuits Identifying features: o Constant inputs: the voltages of independent voltage sources and currents of independent current sources are all constant. o The circuit does not contain any switches. All voltages and currents in a dc circuit are constant. Capacitors act like open circuits and inductors act like short circuits. Example: Determine the current, , and voltage, () it ( ) vt , for this circuit. Solution: This is a dc circuit so the capacitor acts like an open circuit. The capacitor voltage, , is the voltage across that open circuit. The inductor acts like a short circuit. The inductor current, ( ) , is the current in that short circuit. Here’s the circuit after replacing the capacitor by an open circuit and replacing the inductor by a short circuit: Ohm’s law gives 30 2.5 A 84 == + and () ( ) ( ) 44 2 . 5 1 0 = V 1

AC Circuits Identifying features: o Sinusoidal inputs: the voltages of independent voltage sources and currents of independent current sources are all sinusoidal at the same frequency. o The circuit does not contain any switches. All voltages and currents in a dc circuit are sinusoidal at the frequency of the sources. Capacitors do not act like open circuits and inductors do not act like short circuits. Example: Determine the current, , and voltage, () it ( ) vt , for this circuit. Solution: This is an ac circuit so the capacitor does not act like an open circuit and the inductor does not act like a short circuit.
