15.3: Simple AC Circuits
In this section, we study simple models of ac voltage sources connected to three circuit components: (1) a resistor, (2) a capacitor, and (3) an inductor. Resistor First, consider a resistor connected across an ac voltage source. From Kirchhoff''s loop rule, the ...

19.6: Capacitors in Series and Parallel
If a circuit contains a combination of capacitors in series and parallel, identify series and parallel parts, compute their capacitances, and then find the total. This page titled 19.6: Capacitors in Series and Parallel is shared under a CC BY 4.0 license and was authored, remixed, and/or curated by OpenStax via source content that was edited ...
21.6 DC Circuits Containing Resistors and Capacitors
RC Circuits for Timing RC RC size 12{ ital "RC"} {} circuits are commonly used for timing purposes. A mundane example of this is found in the ubiquitous intermittent wiper systems of modern cars. The time between wipes is varied by adjusting the resistance in an RC RC size 12{ ital "RC"} {} circuit. circuit.
23.11 Reactance, Inductive and Capacitive
Sketch voltage and current versus time in simple inductive, capacitive, and resistive circuits. Calculate inductive and capacitive reactance. Calculate current and/or voltage in simple inductive, capacitive, and resistive circuits. Many circuits also contain capacitors and inductors, in addition to resistors and an AC voltage source.
14.6: Oscillations in an LC Circuit
It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively. A circuit containing both an inductor (L) and a capacitor (C) can oscillate without a source of emf by shifting the energy stored in the circuit between the electric and magnetic fields.Thus, the concepts we develop in this …

Calculating Parallel RLC Resonance Circuit
Like series circuits, parallel RLC circuits (containing inductors and capacitors) are second-order with a resonant frequency.. Both are affected by frequency changes. However in parallel resonance, it is the current through the circuit that reaches a minimum at resonance, not the impedance.. The focus here is, how currents in each …
19.2 Series Circuits
Other possible circuit elements include capacitors and switches. These are drawn as shown on the left side of Figure 19.12. A switch is a device that opens and closes the circuit, like a light switch. ... Figure 19.12 On the left is an electrical circuit containing a battery, a switch, and a capacitor. On the left is the analogous water circuit ...
8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. ... the current …
21.6 DC Circuits Containing Resistors and Capacitors
RC Circuits. An circuit is one containing a resistor and a capacitor . The capacitor is an electrical component that stores electric charge. Figure 1 shows a simple circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged ...
8.1 Capacitors and Capacitance
The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, …
Capacitance in AC Circuits
Capacitance in AC Circuits – Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only. Like resistance, reactance is also measured in Ohm''s but is given the symbol X to distinguish it from a purely resistive value. As reactance is a quantity that can also be applied to Inductors as well as Capacitors, …
