There's nothing to calculate. Until it fails and must be replaced, the resistance of
a capacitor is infinite. A measurement with a typical ohmmeter will show that the
capacitor is open.

Can a capacitor be used in the Thevenin Theorem?
Sure, but it won't mean anything unless the Thevenin source is an AC source. In that case, simply determine the frequency of the source, and draw the appropriate reactance in the circuit where the capacitor belongs. If the Thevenin source is DC, then the frequency is zero, the reactance of the capacitor is infinite, and you can show it as an open circuit, i.e. not there.
Which one of the following equations could be used to calculate the power absorbed by a resistor?
p=I*I*R ,P=V*V/R;where I is the current passing through the resistor, and V is the voltage across resistor, and R is the Resistance of the resistor,

What is another name for fluid friction?
air resistance
Is calculate a verb?
yes.
What is insulation resistance in capacitor?
ideally there will not be any resistance to the capacitor,so at this condition it should not not discharge the stored energy. but practically small resistance will be there in the capacitor so the energy stored by the capacitor will be discharged through resistance.
What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
Do capacitors have internal resistance?
1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.
What is the difference between a resistance and a capacitor?
resistance refers to the resistance of flow of electric current wile a capacitor is an electric device that stores energy.
The effect of resistance on the rate of charging or discharging a capacitor?
If the resistance is in series with the capacitor, the charge/discharge time is extended.

Why initially capacitor taking more current?
Consider the instantaneous DC analysis. Initially, the capacitor has zero resistance. You apply a voltage and current is controlled by other resistive elements alone. As the capacitor charges, its effective resistance rises. This adds to the net resistance in the circuit, reducing current. At full charge, the capacitor has infinite resistance, so there is no current. Remember that the equation for a capacitor is dv/dt = i/c.
How do you measure the resistance of the capacitor?
A: Nobody can with an VOM
When does a capacitor act as a resistor of infinite resistance?
When the frequency is zero(i.e when dc power is supplied), capacitor is open is treated as open circuit having infinite resistance.
How long will it take to fully charge a capacitor in a series RC ciRCuit with a 6microfarad capacitor 2Kilohm resistor and 141 volt supply?
The time it takes to fully charge a capacitor depends on the capacitance and resistance of the circuit; the voltage is irrelevant. The equation you need is:t = 5RCwhere: t = time in seconds, R= resistance in ohms, and C =capacitance in farads.So you should now be able to calculate the time for yourself, but remember to convert the resistance into ohms and the capacitance into farads before you insert the figures into the equation.
Why would there be a gain when you add the emitter capacitor to a circuit board?
A capacitor has lower resistance (impedance) as frequency increases. Adding an emitter capacitor effectively lowers the emitter resistance as frequency increases. Since gain in a typical common emitter amplifier is collector resitance divided by emitter resistance, this decrease in emitter resistance will increase gain as frequency increases.
What is a pure capacitor?
whose resistance=0,inductance=0
