Everything You Need to Know About Capacitor Polarity
A special type of electrolytic capacitor, tantalum capacitors are renowned for their use of tantalum as the anode material, providing high capacitance and low ESR (Equivalent Series Resistance). They are suitable for applications requiring high performance and stability, such as mobile phones, computers, and medical devices.
How To Test a Capacitor
This is an article showing a user how he can test a capacitor to see if it is good or defective. We go through several different tests, all using a multimeter. We do resistance checks using an ohmmeter, voltage checks using a voltmeter, and capacitance checks using a capacitor meter. We show in this article how all these tests can check whether a capacitor is good …
operational amplifier
Generally, such a capacitor produces a pole due to the finite output resistance of the opamp. If this pole is low enough in frequency, then the open-loop gain …

OverviewIntroductionNatural responseComplex impedanceSeries circuitParallel circuitSynthesisSee also
A resistor–capacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors. It may be driven by a voltage or current source and these will produce different responses. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit. RC circuits can be used to filter a signal by blocking certain frequencies and passing others. Th…

As the capacitor''s reactance is the smallest of the three components, it dominates the equivalent impedance at this frequency. 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.
RC cut-off frequency, online calculator
Calculation of the cut-off frequency of a capacitor-resistor circuit ... This function can be used to calculate the cutoff frequency of a capacitor and a resistor, or the capacitance or resistance at a given frequency. Two of the values must be known in order to calculate the third. Calculate cutoff frequency. What should be calculated?
