Lead the voltage waves

A: TO measure the current on any path you will need a very small known resistance in sires and measure the voltage drop across it. If the resistance i not small then inaccuracy of reading will be evident

An AC drive is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. AC drives are used in applications ranging from small appliances to the largest of mine mill drives and compressors.

Engineering technicians use the principles and theories of science, engineering, and mathematics to solve technical problems in a variety of engineering fields. Engineering technicians generally have 2 year associates degrees. A lot of techs just install or help engineers with the hands-on start-up or troubleshooting of systems & equipment.

Electrical engineering technologists assist engineers in the design, drafting, and technical skills to implement engineering ideas. EET's generally possess a 4-year bachelors degree. Although the term can be somewhat misleading, someone with a BS in Electrical Engineering Technology can obtain the same job as someone with a BSEE. The EET degree usually focuses on the implimentation of design, while EE focuses on design and theory. The EE degree generally contains higher level math courses than the EET degree.

An emf is induced in a coil as a result of (1) a coil cutting through a magnetic field, or (2) a magnetic field cutting through a coil. As long as there is relative motion between a conductor and amagnetic field, a voltage will be induced in the conductor. That part of a generator that produces the magnetic field is called the field. That part in which the voltage is induced is called the armature. Forrelative motion to take place between the conductor and the magnetic field, all generators must have two mechanical parts - a rotor and a stator. The ROTor is the part that ROTates; the STATor is the part that remains STATionary. In a dc generator, the armature is always the rotor. In alternators, the armature may be either the rotor or stator. ROTATING-ARMATURE ALTERNATORSThe rotating-armature alternator is similar in construction to the dc generator in that the armature rotates in a stationary magnetic field as shown in figure 3-1, view A. In the dc generator, the emf generated in the armature windings is converted from ac to dc by means of the commutator. In the alternator, the generated ac is brought to the load unchanged by means of slip rings. The rotating armature is found only in alternators of low power rating and generally is not used to supply electric power in large quantities.

not sure what your asking is even a question - more a collection of words with a question mark at the end but this may be relevant to your ques... i mean words..

Torque per se does not affect a car's acceleration ability. The spread of torque between the engine's maximum speed and the corresponding speed for the next higher gear does. If your car drops significantly from its torque peak when you change gear (that's you, Celica VVTi) then that can affect your acceleration.

All the talk in magazines about torque being important in the real world is because most people are conditioned by the government to drive at low engine speed, and expect to be able to accelerate hard from low revs. In reality a more powerful car will always be faster than a less powerful car, regardless of their respective torque outputs, given the proviso above, if driven to the engine's power peak.

In respect of the RX-7, which is beautifully geared to drop neatly into the meat of secondary turbo boost for every new gear, you can rest assured that the relatively low torque output is completely irrelevant so long as you rev to just short of the bleeper.

And, let's face it, that's what you'd do anyway right?

HP is rated at 255bhp on paper however due to a gentlemans agreement between auto makers in japan at the time Mazda lied about the power output. Cars tested leaving the factory were found to be more like 300+bhp in the higher spec models (R1 / R2 models)

at the time in japan all major car makers agreed they wouldn't make cars more than 255bhp. hence why Mazda embelished the truth somewhat.

hope this helps, as you can tell i have an awfull lot of time on my hands.

"Full locked amperage" or "Full locked start-up Amperage" is what I was taught.

A voltage drop of no more than 3% is typically allowed for feeder circuits in residential and commercial installations. This helps ensure that the voltage level at the load remains within an acceptable range for proper equipment operation.

I have never heard of any electric fence being more than ten thousand volts, however the voltage is not important --- it's the amperage. Amps are a measure of current / conductivity, so a high-amp jolt will kill even at low voltage. This is how tasers can be lethal. This Concentration Camp fences are also a continuous-current fence which is never done in normal applications. The current is pulsed on-and-off to ensure that you are not lethally shocked; since this is not the case with the Concentration Camp fences, any inmate who touched the fence would form a capacitator, a pathway, through the fence and thereby be unable to let go of the fence. I am not exactly sure of the biology chemistry and physics involved but for whatever reason electric currents cause paralysis, and a really high voltage (powerful) current would probably hold you in place by force. Again don't quote me on that last part, but I think that you can actually suspend someone in mid-air with an electric current (until they boil and explode of course). Yeah, I would say 10,000 volts. But those sadistic freaks might have used more juice, even if it would be economically unsound to do so. 1/2 amps is enough to kill, so they had to be at least 0.5 amps.

KVA means kilo volt amps or kilo Watts. A watt = 1 volt X 1 Amp. Kilo is shorthand for 1000. A watt is a measure of power, which is voltage x amps. Therefore it is not possible to relate voltage to KVA without additional information. Formula wise the above is correct but if you really need the voltage, it can be measured with a volt meter or VOM by putting the test leads across the output terminals of the KVA device.

You may not know this, but Ohm first did the experiment incorrectly and came up with a wrong and very complicated equation for what is now called Ohm's Law. He even published a paper giving this wrong equation.

It was only after the journal in which his incorrect paper was published had been out for some time, that he began trying to replicate the experiment using different equipment. At this point he realized that the type of battery he had chosen for the initial experiments had an unusually high internal resistance, which had caused false readings and resulted in the wrong and very complicated equation.

Use of a different type of battery with a much lower internal resistance in later experiments produced our current correct and simple equation. He then wrote a new paper that retracted the original.

ac voltage

Higher voltages allow for lower currents; electric power is measured in watts, which are calculated by volts multiplied by amps. The higher the voltage, the lower the amperage. This is important as a higher amperage requires a thicker cable; compare the cable on a car battery (12 volts at say, 50 amps, equalling 600 watts) to that on a vacuum cleaner (120 volts at 10 amps, or 1200 watts). The vacuum uses more power, but that power is transmitted through thinner wires, because the voltage is higher. It is the same with long-distance power transmission. Thinner wires are less expensive (they are made of aluminum braided over a steel cable for strength) and also weigh less, allowing the poles/pylons to be of lower strength. Also the losses would be reduced in high voltage transmission.

If the applied voltage exceeds they Max working voltage than capacitor can blow.

You can specify a use for it.

You should probably try it on a small piece first and see how well it works; it seems possible that using a hair dryer could cloud or even discolor the finish, which may or may not matter in your particular application.

It creates an iron bar with wire coiled around it.

It can also create a spring, provided it stays in the same place for long enough so that it holds it's shape.
