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.
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.
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.
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
Voltage amplitude is the maximum value of a 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
Yes, there is a fluctuation of voltage in a moving train
surely , voltage fluctuation Heat
to convert AC into DC voltage without fluctuation
Changes in load results in fluctuations. Fault also results in fluctuation
Fluctuation in voltage of current and excessive heat
noise
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.
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.
Not necessarily. A UPS is primarily designed to produce a short period of power in the case of the mains failing.
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.
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 .
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.
