A: Due to undesirable external voltage changes like the AC line dropping out occasionally the DC or input signal will become a variable voltage that is referred as voltage fluctuation but it can refers to all kinds of these kind of problems.

What are the advantages of a brushless generator?
Brush type generators wear out over time of usage and brushes need replaced at a certain intervals too include any damage caused by pitting or scaring. Brushless generators produce a cleaner voltage sine-wave form verses the brush types. brushless type generators use an additional VCR (voltage control regulator) circuit that maintains a tight voltage level with less fluctuation it should be mentioned such a circuit increase the chances of generator failure due to component failure.
What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
What is knee voltage and breakdown voltage?
Knee voltage (cut in voltage) :-The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage Breakdown voltage :-It is the minimum reverse voltage at which the P-N Junction can conduct without damage to the current
Is there a fluctuation of voltage in a moving train?
Yes, there is a fluctuation of voltage in a moving train
What is the enemy of electrical components in a computer?
surely , voltage fluctuation Heat
Function of power supply?
to convert AC into DC voltage without fluctuation
What causes high voltage fluctuation in domestic power supply?
Changes in load results in fluctuations. Fault also results in fluctuation
What is a common source of IC damage in a computer?
Fluctuation in voltage of current and excessive heat
A fluctuation in voltage levels caused by other devices on the network or electromagnetic interference is called what?
noise
What is the acceptable range of ac voltage at an outlet?
The acceptable range of ac voltage at an outlet is from 115 to 120 volts. The utility company has a mandate to keep the voltage within a 10% fluctuation range. The catch is 10% from what set point voltage.
What will happen to the generator voltage when the load fluctuates in distribution board?
The generator's voltage regulator will sense the fluctuation. If the voltage goes low more current will be applied to the armature to compensate. If the voltage goes high less current will be applied to the armature to compensate.
Does UPS control fluctuation of voltage?
Not necessarily. A UPS is primarily designed to produce a short period of power in the case of the mains failing.
What is the effect of the power less or greater than the range of the allowed power fluctuation?
I assume that you are talking about voltage fluctuation, not power fluctuation? All voltages are expressed as nominal values, and they are allowed to vary from this nominal value by an amount specified in the relevant regulations. For example, in the UK, the nominal value of residential voltage is 230 V (+10% / -6%).Below the allowable limit, some loads will draw excess load current to satisfy their demand, which will increase the line voltage drop, making the situation even worse. Above the allowable limit, the voltage may place undue stress on the insulation leading to its breakdown.
How does voltage fluctuation affect an electrical system?
Whenever you are working over a device and getting a constant voltage supply ,, and all of a sudden .. the light gets off and the device is off. it means a device was working over some specified voltage and it comes to 0 instantly . the voltage changes . this is called voltage fluctuation .
What does a electrocardiograph do?
It measures and records the potentials (e-m voltage) at the surface of your body. These voltage changes are caused by the depolarization of your heart cells acting together - that is, as your heart beats it produces an electrical field fluctuation which can be detected.
