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.

∙ 11y agoInsulation resistance in a capacitor is a capacitor's resistance against DC current flow under steady-state conditions. A higher IR would equal higher resistance against DC current.

What is isolation resistance?
I think you mean, 'insulation' resistance! It's the resistance of insulation, normally expressed in megohms.
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 the load must be removed when to conduct the insulation and resistance testing?
explain why all the load must be removed when to conduct the insulation and resistance testing
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.
When carrying out an insulation resistance test on a walloven with mineral insulated metal sheathed heating elements the minimum permitted insulation resistance is?
0.1M ohms
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.
How do you check the insulation break down value of capacitor?
By testing capacitor tolerance
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 difference between insulation resistance test and polarization index?
Insulation resistance test: This test is used to find the insulation resistance of motor for 1 min or 10 min through high voltage insulation tester. By this we can find the insulation level. Polarization index: This is the ratio between insulation resistance for 10 min to insulation resistance for 1 min.

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.
What is excessive electrical resistance?
High resistance means insulation
How do you measure the resistance of the capacitor?
A: Nobody can with an VOM
What happens to insulation resistance when increasing cable length?
The insulation resistance remains the same throughout the entire length of the conductor.
What is insulation megger draw and explain with neat diagram?
Meggar is a hand driven tool for measuring insulation resistance and earth resistance.
