Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it. The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope).
A: Capacitors can age in storage, particularly electrolytic capacitors, which can experience a loss of capacitance and increased leakage currents over time. Storing capacitors in proper environmental conditions and periodically reforming electrolytic capacitors can help extend their shelf life. Q: Do capacitors store a lot of energy?
A: The energy stored in a capacitor can change when a dielectric material is introduced between its plates, as this can increase the capacitance and allow the capacitor to store more energy for the same applied voltage. Q: What determines how much energy a capacitor can store?
Capacitance: The higher the capacitance, the more energy a capacitor can store. Capacitance depends on the surface area of the conductive plates, the distance between the plates, and the properties of the dielectric material. Voltage: The energy stored in a capacitor increases with the square of the voltage applied.
In theory it will. If an ideal capacitor is charged to a voltage and is disconnected it will hold it's charge. In practice a capacitor has all kinds of non-ideal properties. Capacitors have 'leakage resistors'; you can picture them as a very high ohmic resistor (mega ohm's) parallel to the capacitor.
