What is electric choke?
The choke enriches the mixture for start-up and then is heated by a small electrical heating coil so the choke goes off when the engine is at operating temperature.
How choke coil limit current to the fluorescent tube?
A choke coil, also known as a ballast, limits the current to a fluorescent tube by providing a high impedance to the flow of current. This high impedance restricts the current flowing through the tube, allowing it to operate within its required current range. The choke coil also helps regulate the starting voltage and stabilize the operation of the tube.
Why choke coil is used in tube light?
To limit the current through the lamp when the gas ionises and conducts.
What is the power factor of a coil?
Power factor is the cosine of the phase angle between voltage and current. In a purely resistive load, like a toaster, since the phase angle is zero, the power factor is 1. In a theoretically purely inductive or capacitive load, with the phase angle at 90 degrees, the power factor is 0. Power factor is also the ratio of apparent power versus true power, or watts versus volt-amperes.
What is the difference between electrical choke electronic ballast choke?
Ballast is purely a coil simply inductor that controls the current supplied to the tube. Of which there will be some loss and drop in power factor. Yet it is a good system which can handle the voltage fluctuations in the input. An electronic choke has 2 diode bridges and 2 major capacitors, by which the voltage and current supplied are controlled. The circuit operates in three stages. Voltage boosting is good and immediate, also eliminates starter. But this creates harmonics in the system which may disturb other systems if produced in large and it also cant handle the fluctuations.
What is the power factor of choke coil?
All one can say without more information is that it is less than 1 and greater than zero.
What is ideal choke coil?
An ideal choke coil has only inductance. It has zero resistance and no stray capacitance, therefore no resonances.
What are the parameters of choke coil?
inductance and resistance are the parameters of the choke cil
What are design equations of a choke coil?

What is definition of Q of a coil?
The Q factor (quality factor) of a coil is a measure of its efficiency in storing energy and transferring energy to a load. It is calculated as the ratio of the reactance of the coil to its resistance. A higher Q factor indicates lower energy losses in the coil.
What are the applications of choke coil?
choke coils are various depend upon the specifications it built....for example if u take 0-5 amp choke coil it is used in household applications like for florescent lamps....
What is choke coil?
A choke coil is an inductor, which is designed to block a particular frequency in an electrical circuit while passing signals of very less frequency or direct current.
What is electric choke?
The choke enriches the mixture for start-up and then is heated by a small electrical heating coil so the choke goes off when the engine is at operating temperature.
What is the functioning of choke coil?
A choke coil is used in several electrical devices. The function it has is to block AC currents from passing through as it allows DC currents to pass through.
What is Q factor of a coil?
The Q factor of a coil, sometimes called the unloaded Q factor, is the ratio of the energy stored in the coil to the energy dissipated in the resistance of the wire.
How do you measure Q factor of a coil?
The Q factor, or quality factor, of a coil can be measured by determining the ratio of its inductive reactance to its resistance at a specific frequency. This is typically done by applying an AC signal to the coil and measuring the voltage across it and the current flowing through it. The Q factor is calculated using the formula ( Q = \frac{X_L}{R} ), where ( X_L ) is the inductive reactance and ( R ) is the resistance. Alternatively, it can be measured using the bandwidth method, where the Q factor is derived from the resonant frequency and the bandwidth of the coil's response curve.
What controls the Choke on Briggs and stratton 4.5?
There are several systems used by Briggs for choke control. Auto choke engines are equipped with a heat sensitive bi-metal coil attached to the exhaust. When cold, the coil closes the choke plate. When heated by exhaust gases, it opens the plate. Most other models have a manual lever to open and close the choke or a primer bulb system.
