the source voltage is the voltage that measured exactly after the voltage source , but the terminal voltage is the voltage that measured in the load terminals , which equal to the source voltage minus the drop voltage on the transmission line .

What is a common source for a voltage difference?
Batteries provide a voltage difference.
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
What is the difference between voltage ang current?
voltage: it is the potentail difference between two wires. or it is the amount of energy used to force the electrons.current: it is the flow of free electrons.by Balaji,NITCAnswerThere is no such expression as 'potential voltage'. 'Voltage' is simply another word for 'potential difference'.
What is the effect of internal resistance of the source to its output voltage?
(a) It reduces the amount of current.(b) Any current that does pass the resistor will lose some power; this lost power is converted to heat in the resistance.AnswerInternal resistance acts to reduce the terminal voltage of the voltage source when it supplies a load. This is due to the internal voltage drop caused when the load current passes through the internal resistance of that source. The greater the load, the lower the resulting teminal voltage.By definition, a voltage source's electromotive force is equal to the sum of the voltage drops, including the internal voltage drop, of the circuit supplied.
What is the difference between a terminal moraine and a recessional moraine?
The terminal moraine is the sediment deposition furthest from the source of the glacier. It is also known as an end moraine, however depending on recession or advancement of the glacier, the end moraine is not always the terminal moraine. Lateral moraines are lines of sediment deposited along the outer walls or boundaries of a glacier and can run from the top of the glacier down to its end.
What are independent and dependent sources?
An independent source is a source that produce constant currents and voltage. Dependent sources are voltage sources that depend on a voltage somewhere else in the network.
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 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 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.
The electrode attached to the positive terminal of a voltage source?
cathode
What is a common source for a voltage difference?
Batteries provide a voltage difference.
Difference between voltage and emf?
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
How we can find voltage dropacross a current source?
A current source is an imaginary device that always supplies a constant current, regardless of its terminal voltage.Its voltage is always(the output current from the source) multiplied by (the resistance of the circuit connected across its terminals) .In the terminology of Ohm's Law, you might write E = I RThe voltage drop could also be the difference between 'on load' and 'off load'and is a measure of the internal resistance of the current source.
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
Why peak voltage of the load is smaller than the voltage from the transformer output?
The voltage appearing across a load is always smaller than the no-load voltage of any voltage source -e.g. batteries, generators, or transformers. In simple terms this is because all these voltage sources have internal resistance or impedance which results in an internal voltage drop when the source delivers a load current. The resulting voltage, therefore, is always the difference between the no-load voltage and the internal voltage drop. A measure of the difference between a source's no-load and full-load voltage is termed its 'voltage regulation'.
