when a high power equipment the draws more current initially then comes down will show the affect you questioned. just like motors heaters blowers. intially the put a huge demand for power on source.

Why the alternator voltage drop suddenly and after few second later again pick up automatically during no load?
Overload!
How do you convert hertz into volts?
'Hertz' is the modern name for 'cycles per second' and represents how many times an alternating current (AC) changes from + to - per second and has nothing to do with voltage that can be either AC or DC. Tus if you have an alternator and can rotate the shaft 60 times per second with a voltage of 120 volts you will produce the same AC voltage that you find in your wall outlet (Alternators produce AC while generators produce DC electricity.
Why there is two voltage rating on the same cable like 300V or 500V?
The first figure indicates the phase to neutral or ground voltage and the second is the phase to phase voltage. i.e. Vph-ph = 1.732Vph-n
How could a capacitor have voltage but no current?
Voltage and current are two different things. Voltage is potential energy per charge, in joules per coulomb, while current is charge transfer rate, in coulombs per second. Its that same as saying that a battery has voltage but no current, because there is no load. Well, a capacitor resists a change in voltage by requiring a current to change the voltage. Once that voltage is achieved, there is infinite resistance to the voltage, and thus no current.
How to control the high voltage control in an industry?
Voltage stabilisers are the devices to control voltage. These are of 3 types i.e. VARIAC BASED,IGBT BASED and THERMISTOR TYPE. These are classified according to voltage correction speed i.e. from 70 volt/second to 750 volt/seconds.

Why do the voltage battery light keep coming on after a new battery has been installed?
Ah, you have made one of the most common and easiest mistakes to make in automotive maintenance. Because the 'battery voltage' idiot light came on, you assumed that the battery was bad. Did you have an automotive electrical specialist test the electrical system on your car? Did you have the battery tested at a battery shop? Did you know that there are 3 primary parts to an automotive electrical system, and anyone of them can be responsible for the system operating below required voltage levels? Most modern automobiles generate electricity with a device called an alternator, which is driven by a belt from the crankshaft. The alternator generates Direct Current, at voltages up to 20 volts, in some cases. To keep the alternator from frying the battery, a Voltage Regulator is used to control the output of the alternator. This insures that the battery is only charged with a current of 18 volts, or less. Most modern alterators have the voltage regulator inside, but on older cars, the voltage regulator is mounted on the fender or the firewall, somewhere in the engine compartment. So, the alternator generates the electricity used to charge the battery, but the voltage regulator controls the output of the alternator. If the alternator is going bad, it may not be generating enough voltage to charge the battery. The battery is usually a 12 volt battery, and must see more than 12 volts to charge. Or, the alternator output might be reduced to an unusable level by the voltage regulator. Before you replace the entire electrical system, take the car to an automotive electrical specialist for testing. They can determine exactly which component is not working, and repair it. (Note: If the voltage regulator is bad, this DOES NOT mean that the entire alternator must be replaced! In almost all cases, the voltage regulator can be replaced by disassembling the alternator. If the specialist insists that the alternator must be replaced, I would recommend getting a second opinion, even though testing is often not free. Voltage regulators are fairly cheap, and can be replaced by a competent technician without too much difficulty. Alternators are expensive.)
How can you tell if the alternator on your 2004 grand Caravan has failed?
There are a few things you can try: 1) Take the van to a shop and request that the charging system be tested. If you have them make the necessary repairs, the test is often free. If you are unsure of their trustworthyness, get a second, or even third, opinion from another shop before deciding on who to give your business to. 2) Remove the alternator and take it to an auto parts store. Most of them have the ability to test alternators and normally do it free of charge. Be sure to inquire about whether the alternator employs a built-in voltage regulator and whether that, and not the actual alternator, is the problem. Replacing a faulty voltage regulator (when possible) in your alternator is fairly simple and MUCH cheaper than replacing the entire alternator. 3) Use a volt meter (you may need the help of a second person for a few minutes). Check the voltage across the battery terminals with the engine running at over 2000 RPM (about 3 times faster than normal idle, just guess if you don't have a tachometer). It should be higher than 12 Volts, more like 13-14 Volts and less than 16 Volts. If it is, the alternator is probably fine, the problem lies elsewhere. If the reading is outside those values, have the alternator checked professionally as described in options 1 or 2 above.
Where is the alternator field fuse located on a 1999 Ford F150 5.4L Engine?
The1999 Ford F1 50 pickup truck 5.4 liter engine alternator field fuse can be found in the fuse box. The alternator field fuse will be in the second column, second from the top.

How do you Add a second alternator to car?
You can do this although,Why would you want to? If you need extra power from the alternator then you can buy an alternator that has a higher output. Some cars do not allow you to upgrade to a higher output alternator though (My Mazda Protege5) In this case things get a little more complicated..... You must customize a mount for the second alternator (I removed my AC pump and put alternator there) This way I did not need another belt etc. Just had to make a custom mounting bracket. Then you will need to wire it up, which would be specific to your application.
What is Lightning impulse withstand voltage?
The instantaneous voltage rating of a given insulation sytem. In the case of a lightning strike, it is very high voltage but only for a split second. The insulation is designed to handle this rated voltage for a split second without damage to the apparatus. Any longer, and damage would result.
What is the difference between voltage and power?
Voltage is electromotive force, in joules per coulomb. Power is energy transfer rate in joules per second, also known as watts.Not asked, but answered for completeness sake, and also to show the relationship between voltage and power, current is charge transfer rate in coulombs per second. So, if you multiply voltage (joules per coulomb) by amperes (joules per second) you get watts (joules per second).
Where is the Position of RPM sensor Audi A4V6?
for the most part rpm is counting from alternator (generator) there should be two wires one for rpm second for waking alternator
How many volts equals 50Hz?
Voltage is a measure of potential difference while Hertz is the term we use for cycles per second when we consider rates of change. We might say 50 Hz is a rate of change of voltage equal to 50 cycles of that voltage per second. There isn't a way to "convert" voltage to Hertz.
Where is the voltage regulator in a 1990 Dodge Ram 250?
Sorry to tell you but if someone said to adjust it....that means go buy a new alt. because nowdays there are manufactured with the voltage regulators in the alternators. **The voltage regulator is built-in to the ECM...about a $275 part! However, before you jump to conclusions about the voltage regulator being defective, I'd highly recommend that you go visit the autozone website and follow the "Check charging system" word for word. I discovered that the alternator in my 1990 Dodge van wasn't grounding? How could that be? It's bolted to a metal bracket, right? Could be corrosion, could be rust? I even installed a second ground strap from engine to body. Nothing worked until I ran a ground wire from the battery to the alternator case. Charged just great then! Of course I discovered this after first replacing the alternator and the ECM! Don't you make the same (expensive) mistake.
