Why there is high resistance in experiment of flashing and quenching of capacitor the neon bulb?
Because the product of (the resistance in the circuit) times (the capacitance in the circuit)
is called the "time constant" of the circuit, and it determines how fast the flashing and
quenching will take place. If you want the experiment to proceed slowly enough for you
to watch it happen, then you need a large ' RC ' product. Large-value resistors are
cheaper and easier to get than large-value capacitors designed to operate up to the
firing voltage of a neon bulb, so it's more practical to get a large ' RC ' product by using
a large-value resistor.

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.
Why in the experiment of flashing and quenching of capacitor the neon bulb starts twinkling?
In the flashing and quenching experiment, the neon bulb twinkles because the voltage across the capacitor drops below the breakdown voltage of the neon bulb. This causes the bulb to briefly turn off before the capacitor charges again and the process repeats, resulting in the twinkling effect.
What is flashing and quenching potential for neon lamp?
the potential at which neon bub just start glow is called flashing potential.and quenching potential is a potential at which neon bulb stop to conduct..
How can you tell the difference between a flashing yellow and a flashing red traffic light if you are colorblind?
You can differentiate between a flashing yellow and a flashing red traffic light based on their position and pattern. A flashing yellow light indicates caution and advises drivers to slow down and proceed with care. A flashing red light requires drivers to come to a complete stop before proceeding when safe.
What is flashing pendulum?
A flashing pendulum is a pendulum that alternates between two states, such as swinging to one side and then the other, accompanied by a flashing light or LED to indicate the movement direction. This helps visualize the oscillation pattern of the pendulum.

Why quenching potential is always less than flashing potential?
because flashing potential is potential at which the neon bulb just start conducting or glowing ....while at quenching potential the bulb stops conducting.
What is flashing and quenching potential for neon lamp?
the potential at which neon bub just start glow is called flashing potential.and quenching potential is a potential at which neon bulb stop to conduct..
What mean of flashing and quenching?
"Flashing" refers to a brief, intense burst of light or illumination, often associated with rapid changes in conditions or energy release, such as in photography or fireworks. "Quenching," on the other hand, typically means to extinguish or suppress something, like putting out a fire or cooling a hot material rapidly, often in the context of metallurgy or chemistry. Together, these terms can describe processes where a sudden illumination is followed by a rapid decrease in brightness or energy.
When measuring resistance with a Digital multimeter what does the flashing display indicate?
contact was made.
What is flashing and quenching time?
Flashing time refers to the period during which a material, typically a liquid, transitions to a vapor phase when exposed to heat, such as during combustion. Quenching time, on the other hand, is the duration required to cool a hot material rapidly, such as metal or glass, often to achieve desired physical properties. Both terms are significant in processes like metallurgy and materials science, where controlling temperature and phase transformations is crucial for product quality.
What do you call the flashing white light at parties and clubs?
The flashing white light that may occur at parties and/or clubs is called a "strobe light." A "strobe light" is a high-intensity flashing beam of light produced by charging a capacitor to a very high voltage then discharging it as a high-intensity flash of light in a tube
How can I create a flashing effect in After Effects?
To create a flashing effect in After Effects, you can use the "Opacity" property of a layer and keyframe it to change rapidly between 0 and 100. This will make the layer appear to flash on and off. You can also experiment with adding effects like "Glow" or "Strobe Light" to enhance the flashing effect.
If the car turn signal indicator is flashing fast?
usually it means that one of the bulbs it burned out. Flashers in the circuit need a certain resistance to flash correctly, if a bulb is out there is less resistance in the circuit.
How can I create a visually striking display using flashing LED lights?
To create a visually striking display using flashing LED lights, you can arrange the lights in a pattern or design, vary the speed and intensity of the flashing, and use contrasting colors to make the display more eye-catching. Experiment with different placement and timing of the lights to create a dynamic and attention-grabbing effect.
Characteristics of relaxation oscillator?
A "Relaxation Oscillator" is an "R/C" oscillator, in which a Capacitor is charged from a DC (Direct Current) fixed voltage source, through a resistor. Connected across this Capacitor is a "device" that, initially, does NOT conduct any current. But when the Voltage on the Capacitor reaches a certain value (depending upon the characteristics of the "device") the "device" will "break down" or "avalanche", or suddenly drastically decrease in resistance. This causes the "device" to quickly start to discharge the Capacitor. However, when the Voltage across the Capacitor and its parallel connected "device' decreases with the discharge cycle, the "device" will suddenly return to its "non-conducting" state, and the Capacitor again begins to re-charge. The Capacitor again reaches the "break down" voltage of the "device", and the process continues, thus effectively creating "oscillations". One version of this circuit uses a simple Neon lamp (such as a NE-1) as the "device". Typically, the "break down" or "ignition" voltage of a neon lamp is around 70 volts. At this point, the gas in the lamp "ionizes", becoming highly conductive. However, when this voltage drops (as the lamp discharges the Capacitor) to about 50-60 volts, the lamp "goes out" (the neon gas is no longer ionized or conducting), and the Capacitor again starts to charge through the resistor. This form of the "Relaxation Oscillator" will not operate at high frequencies (such as Radio Frequencies), and was often used to just generate a "flashing light" (the Neon lamp). With the advent of semiconductors, a device called the Unijunction Transistor (UJT) was developed. It contained three leads, the Emitter, Base 1, and Base 2. The junction of the Resistor and Capacitor is connected to the Emitter, with the "bottom" of the Capacitor (and the negative side of the Voltage Source) connected to Base 1 Base 2 is connected to the positive side of the Voltage Source. Again, when the voltage on the Capacitor reaches the "break down" level, the UJT's "resistance" between the Emitter and Base 1 drastically drops, discharging the capacitor. However, when the discharging current through the UJT drops below a certain level, it again develops a high resistance between its Base 1 and the Emitter, and re-charging of the Capacitor begins again. UJT circuits can operate at higher frequencies than the Neon bulb circuit. Often a resistor is inserted between Base1 and the common or negative side of the voltage source, and the resulting discharge current produced voltage across this resistor is used to trigger other devices. Also, the voltage waveform across the Capacitor approaches a linear "sawtooth" waveform (depending on circuit component values), but not nearly as linear as other approaches. "Devices" of this type are considered to have a "negative resistance" characteristic, which is another discussion in itself.
