21.6 DC Circuits Containing Resistors and Capacitors
As charge increases on the capacitor plates, there is increasing opposition to the flow of charge by the repulsion of like charges on each plate. ... A 2.00- and a capacitor can be connected in series or parallel, as can a 25.0- and a resistor. Calculate the four time constants possible from connecting the resulting capacitance and resistance ...
19.3 Parallel Circuits
Resistors in Parallel In the previous section, we learned that resistors in series are resistors that are connected one after the other. If we instead combine resistors by connecting them next to each other, as shown in Figure 19.16, then the resistors are said to be connected in parallel..

$begingroup$ oh so the feedback resistor is there to reduce DC gain! the smaller the resistance, the better it is then. But it also reduces the effective miller RC time constant. But it also reduces the effective miller RC time constant.
8.4: Parallel Circuit Analysis
Note that the plotted resistor and capacitor "currents" are, in fact, the voltages across the associated sensing resistors (nodes 2 and 3) divided by 2 (ohms), in direct application of Ohm''s law. ... being a parallel circuit, there is only one common voltage). Given the voltage, Ohm''s law can be used to find the current through one ...

Why do we have the by pass capacitor parallel to R(E) in this amplifier circuit? They say it is to bypasses the RE resistor for AC signals but then why is it required to by pass the R(E) ... At the moment can you please tell why definition changes when there is emitter resistor. i dont insist. if you have time you may explain this. $endgroup ...
Current split between resistor and capacitor in parallel
At start the capacitor shunts the resistor and you basically get vo = vi (vo is output voltage and vi is input voltage). At steady state there is no current through the resistor so you get a simple voltage …

Resistance of capacitors
A capacitor has an infinite resistance (well, unless the voltage gets so high it breaks down). The simplest capacitor is made from two parallel plates with nothing but space in between - as you can guess from its electronic symbol. In a DC circuit, a capacitor acts as ...
Charging a capacitor in parallel with a resistor?
I''m trying to determine as an exercise for myself the charge on a capacitor as a function of time when a resistor and a capacitor are parallel and connected to the battery. I know I have the wrong answer, but I''m not sure what I did wrong. Through Kirchoff''s loop rule, I

capacitor
Sometimes a resistor, or other load, is added in parallel to a discrete digital input to compensate for the distributed capacitance in a long input cable. Consider the case where a field switch at the end of a long run of shielded cable, has a hot and a return conductor. the other end of the cable pair has a 120 vac Line and the return side …

The answer is yes, but only if the battery is an ideal voltage source, that is, a source without any source impedance. All real batteries …
Does connecting a capacitor in parallel with a wire "short" it out?
I have a question about capacitors. In the circuit below, capacitor C2 is in parallel with a wire. When a resistor is connected in parallel to a wire, the potential across it equals zero so no current goes through it. My …

3.3: Parallel Impedance
By working the capacitive reactance formula in reverse, it can be shown that the reactive portion of (− j161.9 Omega) can achieved at this frequency by using a capacitance of 98.3 nF. That means that at 10 kHz, this parallel network has the same impedance as a 14.68 (Omega) resistor in series with a 98.3 nF capacitor.
8.2: Capacitance and Capacitors
Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance.
