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 …

Measuring resistance with ohmmeter over resistor and capacitor in parallel
$begingroup$ You seem to be assuming that the capacitor starts uncharged - likely a safe assumption, since the parallel R would discharge the C after awhile. I''ve seen ohmmeters display negative resistance when I''ve been too impatient to wait for discharge. And ...
dc
The ideal capacitor has no resistance either in series or in parallel with it. What you are therefore asking about is non-ideal behavior. Truly modeling all the non-ideal characteristics of any real part is impossible. Everything has some series inductance, some series ...

Confusing? Yes - it can be - but doesn''t have to be! An understanding of the basic principles in volved in this concept of "Insulation Resistance" should help to dispel this confusion. When a capacitor is charged from a DC energy source, an initial high current flows ...
ESR and parallel capacitors
So they are not in parallel, you cannot apply the stated law. Of course, if you connect two identical capacitors in parallel they will halve their ESR. The only reason to connect a ceramic capacitor in parallel to a electrolytic one, is to make use of its behavior in

How to measure electrolytic capacitors
Electrolytic capacitors are often used because they deliver relatively large capacitance values in a physically small package. The compact packaging is possible because they use a thin dielectric layer in conjunction with an etching or sintering process that vastly increases the area of the plates and the capacitance associated with them. ...
Parallel Resistor Calculator
The parallel resistor calculator has two different modes. The first mode allows you to calculate the total resistance equivalent to a group of individual resistors in parallel. In contrast, the second mode allows you to set the desired total resistance of the bunch and calculate the one missing resistor value, given the rest. ...

measuring insulation resistance of capacitors
A "real" capacitor consists of an ideal capacitor in parallel with its insulation resistance. This ideal capacitor has infinite resistance at DC. As frequency goes up, however, its reactance decreases according to: X 1 C 2 fC = p where f is the frequency in
Measuring the Internal Resistance of an Electrolytic Capacitor
This is not a very good approach because the value of C is very poorly defined (often +80/-20% tolerance) and your external resistor will necessarily be much higher than the ESR of the capacitor, so I don''t think you''ll have any kind of reliable measurement. You''ll be ...
