Can the terminal voltage rise under which load?
no
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
Why does the terminal voltage decreases as the load current increases?
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
If the speed of the dc shunt motor falls due to loading what will be the effect?
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
How as the blank applied to a circuit increases the power and the current also increase?
answer is actually voltage
Why secondary terminal voltage decreases with increase in load?
An increase in load (equivalent to a decrease in resistance*) causes an increase in load current. This increases the internal voltage drop within the transformer, and the terminal voltage reduces accordingly.[*An increase in load means more current is being drawn by that load, so an increase in load is equivalent to a decrease in load resistance]
What effect if excitation voltage raise on load?
The generator terminal voltage will increase.
What is terminal voltage?
Terminal voltage is the voltage gotten at the terminals of the load in any system.
Why does an alternators voltage drop sharply when it is loaded down with a lagging load?
An alternator's terminal voltage shouldn't drop 'sharply' when subjected to a lagging power-factor load. After all, most practical loads are inductive and it wouldn't do for an alternator's terminal voltage to drop 'sharply' for what is a normal load. Nevertheless, in common with most voltage sources, there will be a moderate drop in its terminal voltage due to the internal voltage drop caused by the load current passing through the impedance of the armature windings. Perhaps surprisingly, however, there may be an increase in terminal voltage when supplying a leading power factor, the reason for which can be demonstrated using simple phasor analysis of the alternator's induced e.m.f. and internal voltage drop -this cannot be shown here, but there are lots of websites which demonstrate this.
Why terminal voltage of a self excited shunt generator decreases with an increase of load?
When the generator is loaded, flux per pole is reduced due to armature reaction.
Can the terminal voltage rise under the load?
no
Can the terminal voltage rise under which load?
no
What is terminal PD?
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
Effect of changing load on alternator?
by changing load its terminal voltage changes.
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
Why does the terminal voltage decreases as the load current increases?
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
