dc
I''m doing an experiment to investigate the internal resistance of an electrolytic capacitor in a DC circuit. Doing this I am measuring the discharge voltage against time, finding tau and from there finding the total resistance in the circuit, which then I subtract the known resistance from to find the internal resistance.

Calculating Capacitance and Capacitive Reactance
The total impedance of the capacitor in an AC circuit with both capacitance and resistance is the series combination of resistance (R) and capacitance (C), which accounts for internal resistance. The voltage phasor (V) across this combination is the phasor sum of the component voltages (VR and VC).
21.6 DC Circuits Containing Resistors and Capacitors
Capacitors, like batteries, have internal resistance, so their output voltage is not an emf unless current is zero. This is difficult to measure in practice so we refer to a capacitor''s voltage rather than its emf. But the source of potential difference in a capacitor is fundamental and it is an emf.
Impedance and Reactance | Fundamentals
The resistance of an ideal capacitor is infinite. The reactance of an ideal capacitor, and therefore its impedance, is negative for all frequency and capacitance values. The effective impedance (absolute value) of a …
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 an open circuit and does not permit current to pass.

4.11 DC Circuits Containing Resistors and Capacitors
The initial current is I 0 = emf / R, because all of the IR drop is in the resistance. Therefore, the smaller the resistance, the faster a given capacitor will be charged. Note that the internal resistance of the voltage source is included in R, as are the resistances of the capacitor and the connecting wires. In the flash camera scenario above ...
