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.
Smith chart with graphical construction for analysis of a lumped circuit. The analysis starts with a Z Smith chart looking into R 1 only with no other components present. As R 1 = 50 Ω {\displaystyle R_{1}=50\ \Omega \,} is the same as the system impedance, this is represented by a point at the centre of the Smith chart.
The signal delay of a wire or other circuit, measured as group delay or phase delay or the effective propagation delay of a digital transition, may be dominated by resistive-capacitive effects, depending on the distance and other parameters, or may alternatively be dominated by inductive, wave, and speed of light effects in other realms.
The following circuit in bridged-T topology is a modification of a mid-series m-derived filter T-section. The circuit is due to Hendrik Bode who claims that the addition of the bridging resistor of a suitable value will cancel the parasitic resistance of the shunt inductor. The action of this circuit is clear if it is transformed into T ...
Thévenin's theorem and its dual, Norton's theorem, are widely used to make circuit analysis simpler and to study a circuit's initial-condition and steady-state response. [ 8 ] [ 9 ] Thévenin's theorem can be used to convert any circuit's sources and impedances to a Thévenin equivalent ; use of the theorem may in some cases be more convenient ...
Small-signal modeling is a common analysis technique in electronics engineering used to approximate the behavior of electronic circuits containing nonlinear devices with linear equations. It is applicable to electronic circuits in which the AC signals (i.e., the time-varying currents and voltages in the circuit) are small relative to the DC ...

Capacitive coupling from high-voltage power lines can light a lamp continuously at low intensity. In its simplest implementation, capacitive coupling is achieved by placing a capacitor between two nodes. [1] Where analysis of many points in a circuit is carried out, the capacitance at each point and between points can be described in a matrix form.
