Take it to an auto parts store; they usually test 'em for free.

== == Yes, there are 3-way dimmer switches.

Normally staircase lights plus bed room lights need these kind of 3-way

switches to turn lights on or off from more than one place. Such lighting arrangements can use dimmers if u need as usual nothing to worry. A dimmer will help save energy, may prolong the life of the bulbs, and will permit greater variability of the amount of light to be used.

Secondry of CT should never kept open during functioning

Cooling; also the oil will prevent arcing since it has a higher dielectric strength than air.

---------------------------------------------------------------------------------------------------

Actually, there are no moving contacts in a transformer, so (normally) no arcing should occur.

The oil cools the windings by carrying heat generated via current flow away from the windings. The oil is moved either by natural thermo-siphon (the upward movement of a higher temperature substance and downward movement of a cooler substance), or by forced circulation, through cooling fins located on the outside of the transformer shell, where either ambient air or forced air (fans) remove the heat.

Additionally, the oil forms a moisture barrier between the transformer windings and the outside air, preventing insulation breakdown and the potential for primary-to-secondary or turn-to-turn shorts.

The 3 phase electric power is very common way of electric power transmission. Three circuit conductors carry three alternating currents the first conductor as reference the other currents are delayed in time for 1/3 and 2/3 of the cycle of the electrical currents.

Clamping voltage, also referred to as let through voltage or the Voltage Protection Rating (VPR), is the amount of voltage a surge protector permits to pass through it to the attached load (ex: a TV) during a surge event.

CDI stands for Capacitor Discharge Ignition system

it is an ignition system and also filters the fuel before it enters the engine which is affective

First of all, the CDI does NOT filter the fuel -that's what the fuel filter is for! And more specifically, the CDI or Capacitor Discharge Ignition box is a small electrical device which consists of a small transformer, a charging circuit, a main capacitor, and triggering circuit. How it functions is this,

First, the transformer takes the normal 12 volts DC from your system and steps the voltage up to around 400 to 600 volts.

Then the current which has been increased, flows through the charging circuit to charge the main capacitor. Inside the charging circuit there is a rectifier which prevents the capacitor from discharging prematurely

Once the triggering circuit receives the triggering signal from the stator, the triggering circuit temporarily stops the charging circuit, allowing the capacitor to discharge it's stored energy very rapidly to the ignition coil.

Then the ignition coil can do it's job of once again stepping up the capacitor's discharge of around 400 to 600 volts up to around 40 kV at the spark plug! Once the capacitor discharges to the ignition coil, it repeats the process again and again.

Lastly, you misused the word "affect" -you were probably meaning "effective"... learn your grammar, son!

I'm guessing this is in reference to a restricted earth fault, and you want to know what the opposite is? Restricted earth fault protection is designed to operate for earth faults within a specific zone. Unrestricted protection will operate for faults "anywhere", as long as the pickup can be satisfied.

For example, REF (restricted earth fault) transformer protection looks for a small amount of neutral current, and if this exists, and the relay identifies this current as being within the zone of protection, the relay will trip. If it were unrestricted, the small amount of neutral current alone would be enough to cause a trip.

lower gears you can also add an new intake which will give your 10-20 more horse powers

the current which has negative value n passes through the diode is called as diode reverse current

Short circuits cause extreme amounts of electrical and mechanical stresses on equipment. Equipment that will regularly carry 100amps of current can be exposed to thousands of amps of current. transformers explode, lines vaporize, poles start on fire, etc. if short circuits are not removed as soon as practical.

An electrolytic capacitor uses an electrolyte (ions in a solution) to store charges.

Many, but a near guaruntee would be any power supply. Electrolytic capacitors are the ones that look like batteries.

An inverter is designed to provide an AC voltage from a battery or DC supply. The AC voltage provided varies in waveform makeup from a square wave to a true sine wave. In between the two extremes are the multi step devices that have as many steps in their modified sine wave as they have switching devices needed to provide each step. Multi step inverters with as many as 48 steps have been manufactured to produce a relatively clean AC waveform.

Single phasing occurs when one or two of the fuses protecting the load fault open. This is likened to using two legs from a three phase source to provide two single phase feeds, hence the name.

A: Believe it or not they all have these components

primary winding and secondary winding how this turn.

No. Transformers are used in circuits with Alternating Current.

Transformers work on the principle of a "changing" magnetic field inducing a current in a conductor, and you don't get that "changing" field with Direct Current.

A: Any zener connected in series will have each voltage added to the load. Therefore each will add 8 volts to the sum of 24 volts. there will be available at each junction as 8v 16v and finally 24volts

The conversion from one DC voltage to another requires electronic circuitry.

Joseph Newman found that "free energy" could be obtained from vortex motion by electromagnetic fields spinning like Tesla claimed. Like other vortex generators, Newman's apparatus appeared to produce energy out of nowhere and the input could be used to deliver free energy. Different physicists had tested his device and confirmed that the input power in the test was 7 and 14 Watts yielding efficiencies of 700% and 1400% respectively.

In 1987 Newman had his generator operating as the engine of a car built on a Porsche chassis. Started by a battery the car ran without any input of fuel at high speed the same results Tesla achieved with his 1931 Pierce Arrow.

However, the American Patent Office refused to grant him a patent for his invention on the grounds that it was, to all intents and purposes, a perpetual motion machine, and herby not possible! Consequently the commercial development of his engine was effectively blocked. The same thing happened toTesla.
