### Why internal resistance of an ideal voltage source is zero and an ideal current source is infinty?

Current source means current generator for a circuit. An ideal current source gives all current to the circuit, but practically a current source does n't give all current to the circuit, instead, a source resistor is connected in parallel to the current source to indicate the current drop.

### What is Impedance of ideal voltage source?

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

### What is practical voltage source?

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.

### What is internal resistant of a DC source?

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.

### What is the value of internal impedance of ideal current source?

internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source

### What is difference between ideal current source and practical current source?

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).

### Why the resistance of a current source is zero?

It isn't. The internal impedance of a current source is high. In an ideal one it would be infinite. A voltage source, however, has a low internal impedance, ideally zero ohms.

### What is the difference between ideal and practical voltage 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

### What benefit is there for getting higher open circuit voltage?

There is no particular benefit for having a higher open-circuit (or 'no-load') voltage. In fact, an ideal voltage source would have no internal resistance and, therefore, its open-circuit voltage would be identical to its closed-circuit voltage.

### What is meant by the internal resistance of a battery?

There is internal resistance in a battery because a battery is not an ideal voltage source. It may be close, but it is not ideal. As a result, analytically, there will be some series resistance, resistance which places a limit on the maximum current that the battery can provide. While no battery is ideal, most are sufficiently ideal to not require any consideration of the internal resistance. If your circuit is dependent on the internal resistance of a battery, then it is probably not well suited for that application.

### What is Difference Between Current Source and 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).

### What are ideal current and voltage sources?

Sources without internal resistances.ideal voltage source has 0 ohms in series with it, no internal voltage drop all voltage delivered to loadideal current source has infinite ohms in parallel with it, no internal current loss all current delivered to load
