  2. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    In the short-time limit, if the capacitor starts with a certain voltage V, since the voltage drop on the capacitor is known at this instant, we can replace it with an ideal voltage source of voltage V. Specifically, if V=0 (capacitor is uncharged), the short-time equivalence of a capacitor is a short circuit.

  3. Two capacitor paradox - Wikipedia

    en.wikipedia.org/wiki/Two_capacitor_paradox

    There are several alternate versions of the paradox. One is the original circuit with the two capacitors initially charged with equal and opposite voltages + and . [4] Another equivalent version is a single charged capacitor short circuited by a perfect conductor. In these cases in the final state the entire charge has been neutralized, the ...

    en.wikipedia.org/wiki/Mesh_analysis

    Figure 1: Essential meshes of the planar circuit labeled 1, 2, and 3. R 1, R 2, R 3, 1/sC, and sL represent the impedance of the resistors, capacitor, and inductor values in the s-domain. V s and I s are the values of the voltage source and current source, respectively. Mesh analysis (or the mesh current method) is a circuit analysis method for ...

    Then the resistance seen by the test voltage is found using the circuit in the right panel of Figure 1 and is simply V X / I X = R 1. Form the product C 1 R 1. Add these terms. In effect, it is as though each capacitor charges and discharges through the resistance found in the circuit when the other capacitor is an open circuit.

    Simple capacitor-start single-phase motor circuit diagram. [3]: 12 Note that starting capacitor is connected in series with auxiliary winding just like in LC circuit. Capacitor motor with a speed limiting governor device. Start capacitors lag the voltage to the rotor windings creating a phase shift between field windings and rotor windings.

    A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's law. An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances ...

    Analyzing the circuit of the lamp shown in the image, at 50 Hz, the 1.2 μF capacitor has a reactance of 2.653 kΩ. By Ohm's law, the current is limited to 240 V/2653 Ω ≈ 90 mA, assuming that voltage and frequency remain constant. The LEDs are connected in parallel with the 10 μF electrolytic filter capacitor.
