Does the charge that flows into the capacitor during the charging process go all the way through the capacitor and back to the battery's or does it get stored somewhere in the capacitor?

A capacitor stores electrical charge. When the device is shut off, the charge will - over time - slowly bleed off. But immediately after shutdown, the charge is still present in the capacitor. In large capacitors, such as those found in air conditioning units, older style televisions, and microwave ovens, the stored charge can be strong enough to be potentially lethal. Service technicians have safe procedures for bleeding off the capacitor charge, but those not knowledgeable about electrical systems should not touch a chassis of above-mentioned items, even if shut off and unplugged. Stickers that say "Danger - High Voltage" mean exactly what they say.
Another Answer
A capacitor does NOT store charge; it stores energy.
The net charge on the plates of a capacitor is no different whether it is 'fully charged' or 'fully discharged'. It does not take charge from the supply and store it on its plates! It simply allows electrons from one plate to be transferred to the other, so there is no change in the overall amount of charge.
What it does do is to store energy, expressed in joules.

Explain the Potential across the resistor during the charging and discharging process of the capacitor?
The voltage across a capacitors given as a time constant t= 63% the resistor value multiply buy capacitor value. it doesn't matter if it goes more or less negative it will follow this function
What is the use of capacitor in touch operated system?
Capacitors are used on touch screen technology. mystery of using capacitor in touch screen is the working principle of capacitor . when you touch the screen the distance between two plates inside screen will change(by pressing) and this will cause the change in capacitance and hence in voltage and this signal fed to processor to process it. and that behind the use of capacitor in touch screen.

What does the control module do on an electric scooter?
Controls the application of voltage to the motor to control speed and direction of the motor. If there is a built in charger it would also control the charging process.
Why does a capacitor block DC and not AC?
A capacitor consists of two plates separated from one another by an insulator. These plates are normally thin foil and can be sandwiched around a very thin insulator and wrapped into a small package. Since there is an insulator between the plates, DC connected to the two plates cannot flow as long as you do not exceed the breakdown voltage of the insulator. AC current is a different story. Because the insulator is very thin and the effective plate area is relatively large, a negative charge building up on one plate causes electrons to be repelled from the opposite plate, and as the charge on the first plate reverses and becomes positive, the electrons in the opposite plate are attracted back again. This results in a matching alternating current flow on the opposite side of the capacitor. actually what happens, capacitor provides a reactance to current. Xc= 1/ (2*pi*f*c) ,where pi=3.14, f=frequency , c=capacitance vaue as dc current is independent of frequency so Xc becomes infinite so dc current gets infinite resistance. so it is blocked
Why capacitor charges exponentially why not linear?
because as the capacitor starts charging,the charges which are already built on capacitor opposes the further flow of charges. hence the process gets slow. thats we get sharp curve initially which gets flat further.
Why high value resistor should be connected in series with capacitor during charging or discharging process?
A resistor is used to limit current flow through a capacitor.If you did not use the resistor, you could potentially create large currents through the capacitor, damaging it. Capacitors do have current limit ratings - check the specification sheet for the capacitor.Also, in the case of an electrolytic capacitor, if it is generally in a discharged state then it is necessary from time to time to reform it. That process involved slowly charging it, i.e. through a resistor, and then letting it discharge by itself with no or little load. The resistor protects both the capacitor and the voltage source in the case that the capacitor might be shorted.
How do timers work?
A resistor is connected between a voltage source and a capacitor, charging the capacitor slowly over a time. The actual time depends on the resistance value of the resistor and the capacitance value of the capacitor. Together they produce something that is described as their "time constant value". The 555 measures the capacitor voltage as it increases and compares it to a threshold to trigger things at certain time intervals, and also 555 has a circuit to discharge the capacitor and restart the charging process. By using clever circuit connections, a 555 with a resistor and capacitor can be used to generate pulses, delays, and periodic signals like pulse trains and low-speed clocks for digital circuits.

What is a CDI?
CDI stands for Capacitor Discharge Ignition system it is an ignition system and also filters the fuel before it enters the engine which is affective First of all, the CDI does NOT filter the fuel -that's what the fuel filter is for! And more specifically, the CDI or Capacitor Discharge Ignition box is a small electrical device which consists of a small transformer, a charging circuit, a main capacitor, and triggering circuit. How it functions is this, First, the transformer takes the normal 12 volts DC from your system and steps the voltage up to around 400 to 600 volts. Then the current which has been increased, flows through the charging circuit to charge the main capacitor. Inside the charging circuit there is a rectifier which prevents the capacitor from discharging prematurely Once the triggering circuit receives the triggering signal from the stator, the triggering circuit temporarily stops the charging circuit, allowing the capacitor to discharge it's stored energy very rapidly to the ignition coil. Then the ignition coil can do it's job of once again stepping up the capacitor's discharge of around 400 to 600 volts up to around 40 kV at the spark plug! Once the capacitor discharges to the ignition coil, it repeats the process again and again. Lastly, you misused the word "affect" -you were probably meaning "effective"... learn your grammar, son!
Application of capacitor?
A capacitor in its simplest form is merely two electrically conductive plates separated by an insulator from each other. As such the capacitor will block any DC voltage from passing through it, up to the electrical dielectric strength of the insulator. The capacitor will accept a DC charge and an electrical field will exist between the plates of the capacitor. The capacitor will retain this charge until it either leaks away via the high electrical resistance of the insulator, or is intentionally discharged. When an AC or varying voltage is applied to a capacitor, a varying electrical field is set up between the plates of the capacitor. This will thus pass through the capacitor, and can be seen on the opposite plate. Thus, a capacitor will pass an AC voltage. Now,as to the question, " application of Capacitor". One of the oldest and most useful of capacitor applications is filtering or smoothing the output of an AC to DC power supply. In this supply, an AC voltage is rectified by a diode into a varying DC voltage. A capacitor is placed across the output, and serves to supply voltage or "fill in" the output whenever the output voltage is less than the capacitor. The capacitor subsequently recharges on the next cycle and repeats the process. Thus, the output voltage of the power supply is smoothed out.
