Another common capacitor type is the film capacitor, which features very low parasitic losses (ESR), making them great for dealing with very high currents. There''s plenty of other less common capacitors. Variable capacitors can produce a range of capacitances, which makes them a good alternative to variable resistors in tuning circuits. Twisted ...
Capacitance Measurements
The accuracy of the reactance-type measurement is less for capacitors that have a high power factor. In capacitors with high power factors, the losses incurred effectively place a certain amount of resistance in series with the capacitive reactance. The effect of this resistance, when the capacitor is measured, is to cause a greater voltage ...
How to test a capacitor: 5 ways with and without a multimeter

Figure 7 shows the result of a measurement to an 100 pF capacitor. On the basis of this measurement is shown how the results should be processed. The following values are measured: the generator voltage V g (5.076 V), the voltage across the capacitor V x (3.242 V), the phase angle between these two voltages α (48.89 °) and the frequency f (50 ...
Capacitance Measurement
A capacitive measurement circuit measures the impedance through an oscillating circuit. Since a capacitor is an effective break in a circuit within a DC environment, charge builds up on the plates of the capacitor, causing a charge imbalance—and then the system stabilizes.

Modern electrolytic capacitors use a standardized measurement method to determine their capacitance. This method is 20°C and 0.5VAC at either 100 or 120Hz (which is derived from the traditional common usage of electrolytic caps, which was to smooth the output of a bridge rectifier. That ripple is going to be 2*50Hz or 2*60Hz, depending on the ...

How to Measure Capacitance using a Multimeter?
A multimeter measures the capacitance by charging the capacitor with a known current. It basically measures the rate of rising of the voltage across the capacitor. The rate of voltage is inversely proportional to the capacitance. IC = C dV/dt.
measurement
There are many different ways to test capacitors. Using a capacitance meter, using a DMM and an analog meter. In general, is it safe to assume that a capacitor is considered functional if it''s capacitance measurement is +- 20% of it''s declared value without doing the ohm/voltage test? Are these test overkill after the capacitance value has been verified?
