in case of ideal voltage source we consider the internal resistance to be zero.but in practical,every battery has some internal resistance then if you connect a load resistance across the terminals of that source,the net potential difference's across the voltage source will be a function of external resistance connects it won't give constant voltage across it's terminals.
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.
Yes.Source transformation in dependent voltage source can be solved the same like independent voltage source
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
A voltage source is anything that provides a voltage; for example a cell or battery, or an electrical outlet in your home.
Internal resistance. The ideal current source has no internal resistance in parallel with it (if it was set to supply no current it would act as an open circuit), and all the current it supplied would have to flow through its load (even if the load was an open circuit, in which case the voltage across the current source would be infinite). A real current source has the practical limitation that it must have an internal resistance in parallel with it, therefor some of the current it supplied is bypassed through that internal resistance and never reaches the load (if the load was an open circuit, then all the current supplied is bypassed and the resulting voltage drop across the internal resistance limits the voltage across the current source).
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
An ideal voltage source is a theoretical concept used in electrical engineering and circuit analysis. It is a voltage source that maintains a constant voltage output regardless of the current flowing through it or the load connected to it. In other words, an ideal voltage source has zero internal resistance and can supply infinite current at a constant voltage. In contrast, a practical voltage source is a real-world device that has internal resistance and cannot maintain a constant voltage output when a load is connected to it. The voltage output of a practical voltage source will decrease as the current flowing through it increases, due to the internal resistance of the source. As a result, the voltage across the load will be less than the voltage output of the source, and the difference is known as the voltage drop. In practical applications, it is important to take into account the limitations of practical voltage sources and design circuits that can operate within these limitations. An understanding of the behavior of both ideal and practical voltage sources is essential for designing efficient and effective electrical circuits. You also read more at electronicsinfos. com
An ideal voltage source has zero internal resistance so that the voltage stays constant with any load current. A practical voltage source should have less than 5% voltage drop at the rated load current.
A: from a voltage source a capacitor will charge to 63 % of the voltage in one time constant which is define the voltage source Resistance from the source time capacitor in farads. it will continue to charge at this rate indefinitely however for practical usage 5 time constant is assume to be fully charged
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
An ideal diode is a simplified model of a diode that does not exist but is used for simple circuit analysis. A practical diode is the real thing. A model of a practical diode used for circuit analysis purposes includes many parasitic components in addition to the diode.
Energy is the source of voltage
when the magnitude of voltage of a source is controlled by another small voltage source in the circuit the former is called voltage controlled voltage source and the later is called controller voltage source.

The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
