How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
Can you test the output amps of a DC generator with no load?
Any voltage source, whether a generator or a battery, will NOT supply an output current unless it is connected to a load. So the only way to test the output current is by connecting it to a load.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
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.
What is the excitation system in a generator used for?
The excitation system is used to control the excitation of the rotating field in the armature. By increasing the armature current, it in turn increases the magnetic flux in the armature coil. This has the effect of increasing the voltage output of the generator. By lowering the armature current this in turn lowers the generator output voltage. The generator's voltage regulator automatically adjusts the output voltage continuously as the applied load on the generator changes.
How it is getting current from generator?
To draw current from a generator, you need to connect a load to it.
Why terminal voltage of a self excited shunt generator decreases with an increase of load?
The terminal voltage of a self-excited shunt generator decreases with an increase in load due to an increase in voltage drop across the internal resistance of the generator. As the load current increases, the drop across the internal resistance also increases, reducing the output voltage available at the terminals. This effect is known as voltage regulation and is a common characteristic of self-excited shunt generators.
What are different between sink current and souce current?
Perspective. They are one and the same, but from the perspective of a load and a generator, the load takes current (sinks it), and a generator generates it (sources it).
How does the load affect voltage output of a series generator?
In a series generator, the voltage output is directly affected by the load. As the load increases, the voltage output decreases due to increased voltage drops across the internal resistance of the generator. Conversely, reducing the load will result in an increase in the voltage output.
In a dc generator why does total flux per pole decrase if the load on the machine increases even thought the field current is constsn?
Due to armature reaction
Why more fuel is required when load of an electrical generator is increased?
It's all about the conservation of energy, and the fact that you don't get something for nothing! As a generator's load increases, the current through the machine increases, so more work has to be done to overcome the resulting increase in 'motor action' caused by the load current. As work is the conversion of one form of energy into another, then more energy must be supplied -and that energy is provided by the fuel supplied to the prime mover.
How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.

In a closed circuit current flow means flow of electrons or charge from genarator to load?
To be more accurate, current flow consists of electrons flowingfrom generator, through load and back to generator.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
