What can protect a computer from problems caused by a change in power?
A surge suppressor will protect against transient high voltage surges.A ferroresonant transformer will protect against transient low voltage brownouts.A uninterruptable power supply will protect against power failures of several minutes duration.
Is 12 volt DC a modified sine wave?
Not really. DC is not a sine wave at all. It is a flat line, in terms of time. On the other hand, if the DC is coming from a power supply that is rectifying AC and filtering it, but not regulating it, then under load conditions, it will exhibit a semi triangular waveform. It will increase when the input AC rises above the diode forward bias point and then it will follow the input AC. It will decrease linearly when the input AC reaches is peak and then starts back down, with a slope proportional to the load. As such, it is a periodic waveform, and by Fourier analysis, it is then a sum of various sine waves. Even if you don't want to get "technical" by looking at Fourier, you can still compare the semi triangular waveform with the input AC waveform, and see that they "fit together". So, yes, 12 volt DC from a power supply is a modified sine wave, unless, of course, there is a regulator stage in the power supply - in that case, it should be flat, as stated first, above.
Can UPS Uninterruptible power supply be loaded with dynamic loads like motors and hydraulic pumps?
That depends on both the UPS and type of motor, so there is no simple answer.Many types of motor will not run correctly unless the AC power is true sinusoidal waveform, and many inexpensive UPS units do not provide a true sinusoidal waveform; so in this case it cannot be done.But in other cases it is possible.
What are five voltages that can be produced by an ATX or BTX power supply Which voltage is seldom used?
What are the 5 voltages produced by and BTX power supply? +12v -12v +5v -5v +3.3v
Advantages of using electrolytic capacitors?
the have large capacitance value, power rating is high , and its constriction. To smooth power supply ripples.The output of a sinewave with the bottom waves cut off is a power supply without smoothing.You would get a hum in an amplifier if it wasn't smoothed by a large capacitance,say 400 Microfarads.On a 12volt supply as in a portable tv,the power supply smoother is around 2000 microfarads.The output waveform should be nearly a straight horizontal line with no ripples on it.

What is a cycloconverter?
A cycloconverter or a cycloinverter converts an AC waveform, such as the mains supply, to another AC waveform of a lower frequency, synthesizing the output waveform from segments of the AC supply without an intermediate direct-current link.
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.
What are the four voltages produced by an AT power supply?
+5, -5, +12, -12
What voltage produced by a atx power supply?
-12, +12, -5, +5 & ground.
How the circuit work of power supply?
A DC power supply is the following components: 1) A step down transformer to reduce the incoming 120 (or 240) V to a lower level, say 12VAC. 2) A rectifier which converts the AC waveform to a pulsed DC waveform. 3) A filter which smooths out these pulses to a more steady-state signal. 4) A voltage regulator, be it a zener diode or LMxxxx voltage regulator, which keeps the output at a consistent level.
Can harmonic produce in the DC circuit?
For non-engineering purposes, a harmonic is a predictable repeating undesired waveform. It usually comes from a type of power supply used in modern electronics called a switching power supply. A harmonic can exist on both AC and DC power. Harmonics can have a seriously detrimental impact on the longevity of electrical devices and systems.
What are the 5 voltages produced by and ATX power supply?
+12V, -12V, +5V, -5V, +3.3V

Is square wave inverter harmful to tvs?
The square wave inverter can be harmful to any device that has an AC to DC power supply, which almost every device does, because the slope of the incoming waveform is higher than usual and the interception point of the ripple waveform with the incoming waveform when the diode turns on can can high current transients in the diode. The can be minimized somewhat by using a series inductor to filter the high current transients.
Why there is no such thing as RMS or watts RMS?
There is such a thing as "RMS power", but it's not useful for anything, so don't use the term. No one measures the RMS of the power waveform. What they do is measure the RMS of a voltage waveform, and then use that to derive the averagepower. The correct term is "average power", not "RMS power". You could measure the RMS of the power waveform instead of the average, but your measurement would be 1.2 times too high.
