What are the causes for the fall in terminal voltage of adc shunt generator on load?
The fall in terminal voltage of an ADC shunt generator under load can be attributed to several factors. Firstly, the armature reaction causes a distortion of the magnetic field, leading to reduced effective field strength. Secondly, voltage drop due to armature resistance and field winding resistance becomes significant when the generator is loaded. Additionally, increased load current can cause saturation of the magnetic circuit, further diminishing voltage output.
What is the effect in output for changing input frequency in halfwave rectifier?
if filtered and loaded the average DC voltage will increase and the ripple AC voltage will decrease, but the peak voltage is unchanged. this is because the filter capacitor has less time to discharge into the load.if unfiltered or unloaded the voltage cannot change. unfiltered the waveform just follows the half cycle of the input. if filtered but unloaded the output is DC at the peak voltage of the input AC.
What is ferro-resonance effects?
The effects of ferro-resonance are the ungrounded primary transformers, higher distribution in the voltage systems. Other effects are the lightly loaded transformers.
Why during loading the voltage get decreased at output?
Output voltage (...of a transformer, for example...) will decrease as it is loaded because of the transformer's internal resistance. As output current increases/load resistance decreases, a larger voltage will be dropped across the internal transformer resistance. This same phenomenon is present in AC and DC systems (such as batteries).
What is the consumption of a 25kW transformer with an 200v input?
The consumption of a 25 kW transformer is determined by its power rating, which indicates the maximum power it can handle. If the transformer operates at its full capacity, it will consume 25 kW regardless of the input voltage, as long as it is designed to operate at that voltage level. The input voltage of 200V is relevant for determining the current drawn, but the transformer's power consumption remains at 25 kW, assuming it's fully loaded.
Why does an alternators voltage rise when it is loaded down with a leading load?
Because in the leading load or capacitive load the armature reaction is magnetizing.Here the stator flux adds up rotor flux and so the net flux of alternator increases and the net flux produces alternator's voltage.Hence the alternator's voltage rises.
What are the factors that cause a change of alternator terminal voltage when it is loaded?
The alternator terminal voltage can change when loaded due to several factors, including voltage drop caused by the internal impedance of the alternator, which consists of resistance and reactance. As the load increases, the current draw rises, leading to increased voltage drop across the alternator's internal components. Additionally, the saturation of the magnetic core can occur as the load increases, further affecting the output voltage. Finally, variations in engine speed and excitation levels can also influence terminal voltage under load conditions.
What cause the voltage drop in shunt generator when its loaded?
because the voltage likes to drop
What is voltage regulation?
Voltage regulation:(from point of view of electrical machines or generator): It is the change in voltage in between the full loaded and no loaded condition. When there are no loads connected the terminal voltage is equal to the generated voltage in the generator. But when load is connected the terminal voltage is found to be lass than the no loaded condition, due to armature resistance leakage reactance.This phenomena is expressed as, % reg=(Vnl-Vfl)/Vfl * 100%.Which is Voltage regulation. ************************************************************ An ideal voltage source has zero internal impedance. A practical one, even a good one, has internal impedance. With no load on the source, the terminal voltage will have a given value. Once a load current is drawn there will be a voltage drop across the source's internal impedance, and the terminal voltage will therefore drop. The higher the load current, the higher the voltage drop. A regulator circuit, added after the source, can counter the effect of the source's impedance and maintain an output voltage which is more constant than the source itself can achieve.

What is residual voltage for DC generator?
This case arises only in series dc generator current should be sent around the poles to magnetize. this current can the source(generator). current is passed through poles if it is loaded. but if it is not loaded current is zero through the field. load voltage should be zero actually.but this dont happen.we use generator frequently.due to this poles are partially magnetized this causes some voltage appear called residual voltageAnswerThere's no such thing as 'residual voltage'; you're confusing it with 'residual magnetism', which exists in the magnetic poles of a self-excited d.c. generator and which enables the build-up of its terminal voltage.
What is the reason for ferranti effect?
Ferranti Effect causes the receiving end voltage to be more than the sending end voltage. It occurs mainly in long transmission lines when they are lightly loaded. In this condition, the inductance of the lines becomes more resulting in increased receiving end voltage.

What is the effect of transformer impedance on regulation?
The lower the impedance, the lower the voltage drop across the transformer as it is loaded. This means regulation is better, since voltage variance is smaller.
Is sharply a loaded word?
"Sharply" is not typically considered a loaded word. It is an adverb that is commonly used to describe the intensity or suddenness of a change or action.
Do XML technologies allow webpages to change after they have been loaded?
YES
