How did the electrical generator change over time?

What does an electrocardiogram measure?

The electrical activity of the heart over time.

What is the function of an electrical engineer in telecom sector?

Electrical Engineer in telecom sector is as important as other Engineer as Civil, Telecom etc, as all the system runs on Electrical but now a days, as per market requirement, you should keep know how about other fileld also. But now a days in different fields every one think that he is misfit and the other is best then him. So we should change over self time to time with respect to the requirement of time.

What does the capacitor in a generator do?

The capacitors in a generator is to store energy produced. They are also needed when starting the generator as a considerable amount of extra power is needed at this time.

Why does a generator always have a sinusoidal waveform?

The interaction between coil and magnetic energy creates a smooth positive and negative electron flow that peaks evenly above and below neutral. When you track this peak and valley change over time, the result is always a smooth sinus wave.

What is loss of excitation in generators?

A loss of excitation will cause the generator to start drawing more and more reactive power over time. Over the first few seconds, and until about thirty seconds after the LOE (depending on the load on the generator before the loss of excitation occurred), active power will stay relatively constant, but reactive power will continue to be absorbed from the rest of the system, and voltage levels will drop. Eventually, the magnetic field between the stator and rotor degrades too much, pole slipping and loss of synchronism will occur. At this point, catastrophic damage will likely have been done to the generator.

How does a change over switch works?

When the supply from GEB is cut away, at that time the consumer is required to change over from the main supply to the private generator, so that he cut the supply from mains and switches to Generator with a change over switch.

Does an electric generator motion produces magnetism or power or electricity?

An electric generator produces electrical energy. It converts mechanical energy to electrical energy by interacting with a magnetic field. The amount of electrical energy converted to useful work in a given time interval is the power output. If the generator is not connected to any load, then no work is done and there is no power.

Do electrical requirements for motherboards change over time as new technologies make additional demands for power?

True

What is an excitation signal?

It is a DC voltage that is applied to the generator's revolving field windings. This produces a magnet field that cuts the generators main coil windings, inducing an electrical current within the main generator windings.

What is an Audio Generator?

Anything that creates electrical sound (aka audio.) A piano is a sound generator but NOT an audio generator. An organ or keyboard is an audio generator and not a sound generator. These can also be thought of as signal oscillators in the 20-20k hz range which usually produce a constant signal or tone over a period of time. Sound is anything you can hear, and audio is anything you need an amplifier to hear.

What does it mean when you say electric charge is conversed?

That means that in a closed system, the total amount of electrical charge won't change over time.

How have valleys changed?

Change over time is referred to as?

A change over time is often referred to as a gradual change.

What is Difference between dual trace oscillosope and dual trace generator?

Oscilloscope is used to display electrical signals on a display. A dual trace oscilloscope can display two signals simultaneously. For a trace generator I think you mean a signal or a function generator which generates electrical waveforms of varying shapes, frequency and amplitude. A dual trace or a function generator in that sense is an equipment capable of generating two independent waveforms at the same time. - Neeraj

Populations change over time due to the process of?
