What is the meant by harmonic distortion in wave analyzers?
distortion refers to any deviation in any parameter like amplitude,time shape of an electrical signal from an ideal input signal.the distortion occurs due to the inherent non-linear characteristics of the component and devices that form the electronic circuit cause some harmonics to take place in the waveform and resultant deviation is know as harmonic distortion.
What the use of SMT in the manufacture of an electronic circuit?
to complete circuit
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.
Can you use electronic circuit as a load?
If you are just using the load to pull a small amount of current, then yes a electronic circuit can be used for that. If you want a resistive load to measure voltage drop or something similar, then no an electronic circuit will usually not work for that.
How do you prevent the excess amount of current flows through the source?
An inrush current preventing circuit includes a rectification circuit, a temperature-sensitive component, a controller, a switching circuit, and a tank circuit. The controller outputs a control signal to turn on the switching circuit in response to the tank circuit being at a substantially full voltage, and the rectification circuit and the switching circuit forming a current loop for providing power from the rectification circuit to an electronic device. The controller outputs no control signal to turn off the switching circuit in response to the tank circuit being undercharged, and the rectification circuit and temperature-sensitive component forming a current loop for providing power from the rectification circuit to the electronic device for protecting the electronic device. the rectification circuit and the switching circuit forming a current loop to provide power from the rectification circuit to the electronic device;wherein the controller does not output a control signal to turn off the switching circuit in response to the tank circuit being undercharged, the rectification circuit and temperature-sensitive component forming a current loop to provide power from the rectification circuit to the electronic device such that an excess amount of current is prevented from flowing to the electronic device

What does an electronic ballast do?
Electronic ballast is designed to limit the current which goes through an electrical circuit. This keeps the circuit from overheating or suffering other ill effects from having too much current.
What is electronic blast for a CFL lamp?
The electronic BALLAST is a circuit that limits the current through the fluorescent bulb to the design value. It also provides a pulse of high voltage to start the bulb conducting when it is switched on.
Describe the effects of complex waveforms on electrical systems?
Because a complex wave is purveyed as a 'distortion', this generally equates to an effect on what output the circuit gives. As the complex wave is, as quoted, the sum of the fundamental and the 3rd harmonic (commonly known as superposition), the nature of the effect on electrical and electronic systems are determined by how distorted the complex waveform is.
What is a distortion analyzer?
A distortion analyzer is an electronic test instrument that measures the accuracy of an electronic circuit at reproducing a wave. For instance, an audio amplifier might have a sine wave input to it, and the distortion analyzer measures how close the output is to a sine wave. If the output is clipped, the wave will be distorted, and the analyzer will measure the amount of harmonics present. The analyzer does this by supplying a low distortion sine wave test signal which is connected to the device under test. The output from the device is connected to the input of the analyzer where the original input signal is filter out with a precision notch filter. Anything left over after filtering represents distortion components and noise. Amplifiers will frequently have a "Total Harmonic Distortion plus Noise" specification which is an accurate term for the quantity measured by a distortion analyzer. There are many manufacturers of distortion analyzers. The Hewlett-Packard models 331a and 333 are laboratory standard instruments. Other notable manufacturers are Sound Technology Corporation and Textronix.
Is low distortion circuit better or 0.5 percent distortion circuit for a home theatre?
When designing, selecting, or operating an audio system, you always want the distortion to be as low as possible.
What does the ballast do in a fluorescent light fixture?
Electronic Ballast plays a important part in lights.We need a Ballast Tester to test the electronic ballast performance of a fluorescent light fixture. This is a basic process that can be accomplished quickly once you understand the operation of the high voltage transformer. The high voltage transformer is also encased in an oil bath that reduces the heat created by the action of the transformer. A low voltage, generally 120 VAC, is transformed into a high voltage, generally in thousands of volts. There must be a continuity between the wires of the high voltage side in order for the circuit to operate correctly. Heat can damaged the internal connections of the ballast. By using a volt ohmmeter the internal circuit can be quickly checked. Not only in the voltage, but also in the current and others factors. If you want to learn more details about electronic ballast and relevant instruments, see the related link.

How many T8 fixtures can go on one 20 amp circuit?
Divide 20A by the Amps listed on the label of each fixture ballast. A T8 bulb will use an electronic ballast. They generally run 1A for four 4 foot bulbs. Try 15 four bulb fixtures per circuit and use a 20A rated switch.
Can you wire a 120 volt ballast to a 347 volt circuit?
No, not a good idea. You have to use a 347 volt ballast.
How distortion can be avoided?
simple.........by changing the circuit parameters
Can T8 LED tube light be used with ballast and can ballast be removed and will it work?
A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.
