generally faults are of symmentrical and unsymmentrical faults that occur in majorly occurs in transmission lines........ the fault in electrical transmission line which give rise to symmetrical fault current is called symmetric fault. e.g; L-L-L-G fault.

if they are in low values then system is said to be "protected" ....

In order to avoid those NEUTRAL SHOULD GROUND with resistor or reactor etc,,,,,,,,...........

it doesn't develop emf ..........

because in a capacitor only charges are stored so the stored charges are gives the zero current

If your question is, "Can a capacitor bank reduce high loads in electrical systems?"

Not really.

In an AC system, a capacitor bank can be used to balance the complex power drawn by the load. If done correctly, this can reduce the current being drawn by the load. If done incorrectly, this can increase the current being drawn by the load.

Look up "power factor correction" for more details.

Generator output is controlled by voltage feedback to the voltage regulator which senses voltage drop or rise and regulates the current being sent to the armature. This rise and fall of the armature current governs the generators output voltage.

The Nyquist stability criterion, named after Harry Nyquist, provides a simple test for stability of a closed-loop control system by examining the open-loop system's Nyquist plot. Under many circumstances, stability of the closed-loop control system may be determined directly by computing the poles of the closed-loop transfer function. In contrast, the Nyquist stability criterion allows stability to be determined without computing the closed-loop poles

Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.

The rubber is insulation; it is to keep the wire from coming in contact with another wire, or grounded equipment, which would result in a short circuit.

A short-circuit test is done to determine the power lost in the resistance of the primary and secondary windings of the transformer. It is done at full load current but with only enough voltage to give the required current with the secondary short circuited.

An open-circuit test is done at full load voltage but no current is taken from the secondary, and this enables the power lost in the magnetic core of the transformer to be measured.

As well a power, the tests also allow the inductances to be measured as well as the resistances, in order ot characterise the transformer fully.

When it's forward biased, carrier dffuses from positve terminal of the v source to the negative terminal ". Whereas in reverse bias mode, minority carrier currents are due to thermal energy only. remember: voltage s d amt of energy needed 4 each charge to pass frm 1 pt to the othr pt.

I think you mean "serging". This is the kind of stitching you see at the inside seams of store bought clothing. It is made with a special sewing machine called a "serger" that uses 3-4 threads at a time and trims the seam as it goes.

Assuming you mean the 4 lamps are in parallel with each other: the total voltage drop across each lamp is still 12V. As we know that V= IR (Voltage = I Current times Resistance)

12 = 1 x R

so Resistance = 12 Ohms for each lamp.

If 1.66A is OK for a 2A rated device, will depend on what you are trying to power up and how much current it actually needs for startup and regular operation.

For colleges and universities that operate on a regular two semester academic year, one credit hour means one hour of classroom time per week. Most courses are three credits. Thus, you are required to be in class three hours per week. Some three credit courses are broken down where they meet three days a week for one hour each day, some meet two days a week for an hour and a half, while still others meet once a week for three hours. If the course is four credits, then you are required to be in class four hours per week etc. This should not be confused with study time outside the class room. The study time will depend on whatever it takes to get a good understanding of your subject content and class assignments.

An autotransformer is no different than a regular transformer. It has "effectively" two windings, a primary and a secondary. Its just that one end of the primary is connected to one end of the secondary. It can also be said that it has only one winding, and that there is a tap someplace in that winding, but the end result is the same. Depending on how it is connected, it can step up or step down the voltage. Some autotransformers have multiple taps. Some, called variacs, have a sliding contact that allows relatively fine control of the output. The up side of an autotransformer is that it can be easier to build. The downside is that it does not provide electrical isolation between primary and secondary, nor can it filter harmonics as well as a dual winding transformer.

In DC inductor is short circuited .

AC. is alternating current and Dc is direct current. alternating equivalant to pulsating electricity while direct is a constant draw with little fluxuation.

Imperviousness to erosion via air at lifted temperatures. In stainless steels, chromium is the most critical component for expanding the scaling resistance particulary at temperatures above 1000°

A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.

60898 is an IEC standard; there are two parts. 1 is for AC, 2 is for DC.

IEC 60898-1 "applies to a.c. air-break circuit-breakers for operation at 50 Hz or 60 Hz, having a rated voltage not exceeding 440 V (between phases), a rated current not exceeding 125 A and a rated short-circuit capacity not exceeding 25000 A."

IEC 60898-2 "gives additional requirements for single- and two-pole circuit-breakers suitable for operation with direct current, having a rated d.c. voltage not exceeding 220 V for single-pole and 440 V for two-pole circuit-breakers, a rated current not exceeding 125 A and a rated d.c. short-circuit capacity not exceeding 10000 A. This Part 2 is to be used in conjunction with IEC 60898-1." (quotes taken from IEC abstracts)

In the US, I've always heard it "AM-peer" (1st syllable like "I am" and 2nd like "pier"). It's actually the name of a French scientist, so I'm sure it's been Americanized.

The plural would then be "AM-peerz".
