Any capacitor that is initially uncharged, when presented with a step change in voltage, will have an instantaneous resistance of zero ohms. As a result, the instantaneous current with a circuit involving 4500 ohms and 500 volts will be about 0.111 amperes. It does not matter what the capacitance is.
The stated voltage in the question is unclear, so 500 volts was assumed for the answer.
The electrolytic capacitor should be connected in only one direction.
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.
Because it is simple phenomenon of electricity everything(resistance,capacitor,inductor) connected in parallel holds the same voltage across the each parallel element.
Ideal capacitors and ideal inductors do not dissipate energy, they store energy and release energy like a spring or pendulum. This type of impedance is called reactance as opposed to resistance. Reactance is represented by imaginary numbers, while resistance is represented by real numbers. Real world capacitors have an Effective Series Resistance (ESR) that consumes a small, usually negligible, amount of energy.
It depends on how the capacitor is connected and whether the supply voltage is a.c. or d.c. Assuming you are talking about a power-factor improvement capacitor (connected in parallel with an inductive load, supplied with a.c.), then the supply current will reduce.
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
an ideal ammeter has zero or negligible resistance when this is connected in series no effective resistance would be added in the circuit so that the value of curret that we get is exactly of the circuit only. but when the ammeter is connected in parllel as it has zero resistance , the resistor to which it is connected in parllel gets shorted and due to his the effective resistance of the circuit is changed and so the effective current ... due to this the w=value measured by the ammeter would be different (incresed due to dec. in effective resistance)
The Capacitor with running winding is connected in parallel with main winding.
The electrolytic capacitor should be connected in only one direction.
when a capacitor is connected to earth the potential of capacitor becomes zero. as a result all the charge residing on the conductors of a capacitor passes away and the final charge on capacitor becomes zero

Resistance is connected in parallel with voltmeter or say, voltmeter is connected in parallel with resistance.
A polarized capacitor will be permanently damaged if connected to the incorrect polarity.
Because it is simple phenomenon of electricity everything(resistance,capacitor,inductor) connected in parallel holds the same voltage across the each parallel element.
When an inductor is suddenly connected in parallel with a charged capacitor, the current through the inductor and the voltage between its ends will oscillate at the frequency of F = 1 / 2 pi sqrt(L x C) . With real-world components, having resistance and connected through wire that has resistance, the amplitude of the oscillation will steadily decrease as energy is lost in the circuit, and the oscillation will eventually become too small to measure, and disappear.
Positive post of capacitor is connected to the heavy amp cable. The ground terminal (or case) of the capacitor is connected to the car's ground or a ground wire that leads to the car's chassis. That's it.
