The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.

Is capacitor discharging time is equal with charging time or not?
The time constant is equivalent to 1/(R*C); since C (the capacitance of the capacitor) is not changing, yes, the charging and discharging times will be the same, provided the Thevenin resistance is the same as well - if you charge a capacitor using a AA battery, then remove the battery, and discharge through a resistor, you have changed the Thevenin resistance, thus the discharge time will NOT be equal.
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.
Compute the reactance of a 2.50 uF capacitor at the frequency of 600?
Do it yourself. The equation is Xc = 1 / (2 pi f C). Be sure to convert microfarads to farards, first!
Why does the reactance of a capacitor decrease with frequency?
Because reactance of capacitor is inversly proportional to the frequency i.e- Xc=1/(2*pie*f*c) where f is frequency and c is capacitance of capacitor.
What can you say to charging and discharging capacitor?
A capacitor will charge at a set time of 63% for one time constant and will continue to do so until fully charged which mathematically will never happen. therefore in the industry a 5 time interval is considered as fully charged.
Explain how a discharging capacitor in an electronic divice produce complex waveform?
Explain how a discharging capacitor in an electronic divice produce complex waveform?
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.

Will a capacitor discharge in a open switch?
if the source is switched off there will be leakage slowly discharging the capacitor
What happen to the energy stored in the capacitor while the capacitor is discharging?
It flows out of the capacitor into the external circuit
How is make capacitor?
Capacitor is nothing but a storage device. It has a dielectric media in between the two electrodes. the nature of the capacitor is charging and discharging the voltage.
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.
What is discharging direction of capacitor?
When a capacitor discharges the discharge current flows in the opposite direction to the current used to charge it.
Why in the experiment of flashing and quenching of capacitor the neon bulb start twinkling?
It is due to the charging and discharging of capacitor in the circuit....
What is the use of diodes in doubler voltage?
A: The purpose it to block the capacitor from discharging to the source
Capacitance is the property of an electrical circuit that?
A capacitor resists a change in voltage, proportional to current, and inversely proportional to capacitance. The equation of a capacitor is dv/dt = i/c.
Define capacitive time constant in terms of charging and discharging?
The product of resistance and capacitance is referred to as the time constant. It determines rate of charging and discharging of a capacitor.
