Two voltage sources in series can either add up or cancel out depending on which way round they are orientated. If the two positive or the two negative terminals are connected together, the overall voltage is the subtraction of the two. If the positive terminal from one supply is connected to the negative terminal from another, the overall voltage is the sum of the two.
That depends on the network, where the voltage sources are in the network, type of voltage sources (DC, AC, signal, noise, etc.)
An ideal voltage source has no internal resistance, and a constant voltage output. In reality, all voltage sources (battery, generator, etc.) have some internal resistance, and their voltage may degrade or change over time.Ans 2: An ideal voltage source will have zero input impedance and the voltage can rise to infinity to supply the current.Read more: What_does_an_ideal_voltage_controled_voltage_sources_do
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
You short a voltage source when doing this analysis because you do not know how much current will flow through the voltage source - consider it an undefined value. For the same reason, you open a current source since you know how much current will be flowing through it. This is a simple explanation; I'm sure a more exhaustive, technical one could be made if this is not sufficient.
No. This would mean more power is used than is provided - an impossibility. It is possible that you may not be accounting for a power source in your circuit, or have the actual source modelled incorrecty.
The speed of a generator only effects the frequency. Most generators operate at 1800 RPM. The output voltage is controlled by varying the field excitation voltage.

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).
Nothing.
Yes, you can use more than one source of voltage in a circuit. You can also use more than one source of current in a circuit. In fact, complex circuit analysis can utilize Norton and Thevanin equivalents to convert part of the circuit from current source to voltage source and vice versa, allowing you to eventually understand the complete circuit.
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.
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
The voltage between the ends of the circuit doesn't change ... that's where the power source is connected. But when you add more items in a series circuit, the voltage across each item changes. The individual voltages across each item in the series circuit always add up to the voltage of the power source. So in general, if you add more items, the voltage across each of the original ones must drop somewhat.
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
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.
You will need to add more details. The voltage will always be 12 volts from a 12 volt source until a circuit is completed, discounting any discharging of a battery.
A: assuming a infinite current source the current will increase accordingly
That's a Parallel circuit.
