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.
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.
Why is there a C in the equation for a discharging capacitor?
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.
What is the effect on charging and discharging times if the capacitance is increased?
The charging and discharge time increases. R*C=T
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.
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.
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.
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.
What is the relationship between resistance and capacitance in a circuit with a capacitor, and how does the resistance affect the charging and discharging process of the capacitor?
In a circuit with a capacitor, resistance and capacitance are related in how they affect the charging and discharging process of the capacitor. Resistance limits the flow of current in the circuit, which affects how quickly the capacitor charges and discharges. Higher resistance slows down the charging and discharging process, while lower resistance speeds it up. Capacitance, on the other hand, determines how much charge the capacitor can store. Together, resistance and capacitance impact the overall behavior of the circuit with a capacitor.
Why in the experiment of flashing and quenching of capacitor the neon bulb start twinkling?
In the experiment of flashing and quenching of a capacitor, the neon bulb twinkles because the charging and discharging of the capacitor cause the voltage across the capacitor to fluctuate rapidly. These fluctuations can cause the neon bulb to turn on and off, leading to the twinkling effect.
What is the relationship between capacitor resistance and the overall performance of an electronic circuit?
The relationship between capacitor resistance and the overall performance of an electronic circuit is that the resistance of a capacitor affects the charging and discharging times of the capacitor, which can impact the timing and stability of the circuit. Higher resistance can lead to slower charging and discharging, potentially affecting the circuit's functionality and efficiency.
Do the time constant remain the same for discharging and charging capacitors?
No, the time constant is different for discharging and charging capacitors. The time constant for charging a capacitor is given by the product of the resistance and capacitance (τ = RC), while for discharging it is given by the product of the resistance and the remaining capacitance (τ = RC).
Why is the charging time of a capacitor lower than the discharging time?
The charging time of a capacitor is usually lower than the discharging time because during charging, the voltage across the capacitor is increasing from zero to its maximum value, which initially allows a higher current to flow. During discharging, the voltage across the capacitor is decreasing from its maximum value to zero, resulting in a lower current flow. This difference in current flow affects the time it takes for the capacitor to charge and discharge.
Why you use CRO to observe the charging and discharging current of capacitor?
using CRO we can measure the rise time and fall time of the capacitor for further studies
Why we get triangular wave as output when we apply square wave as input?
because of charging and discharging of capacitor present in the circuit. beacause capacitor charges exponentially. akshay dabhane

Why capacitors are not connected in series in power line?
capacitor's characteristic is charging and discharging. discharged energy will be dropped by load . so it is connected in parallel
