Is it possible to have an ideal current source in real world?

So to sum this up: There are no real-life objects that can be used to represent ideal voltage and current sources, but there are some objects that can be (in some cases quite closely) represented with ideal voltage and current sources.

Why is it important to use a current source?

When you use current sources you show your readers that you are up-to-date with your topic. Of course, there are times when an older source may help you, especially when you want to establish historical context, but in many writing situations you want to find the most recent information.

Why do we prefer using voltage than current as a data carrier in electronics?

If there is no current flowing through the line resistance, there is no voltage drop (losses) across the line and the end voltage is (almost) equal to the input voltage. Voltage controlled analog circuitry is easier to control in terms of bandwidth, has a lower power consumption and circuit design is more flexible.

Can you have a current source without voltage?

No,there is no current without voltage because according to ohm’s law V=IR where “v” is voltage “I” is current and “R” is resistance. when V=0 then I=0 and R=0 so not possible without current.

Why does an ideal current source have infinite resistance?

Current always takes the path of least resistance. Thus, in order for current to go to the path of least resistance, we must set up the source and load so that the source has much higher resistance than the load. This is why we construct the ideal current source to have infinite internal resistance.

What does an ideal current source mean?

An ideal current source is by definition a two-terminal element with the property that the current flowing through the device is specified at every instant in time. This current does not depend on the voltage across the source.

What are the consequences for not evaluating sources?

Inaccurate, questionable, or out-of-date sources can undermine your ideas and cause the reader to question your authority on your topic.

Why we use voltage not current?

Whenever there is a potential difference between two points, an electrical field is generated and electrons starts flowing in the direction of high potential to low potential. Thus whenever there will be a Voltage (potential difference) there would be a current, depending on the medium and path of course.

Why do we transmit voltage instead of current?

Why High Voltage The primary reason that power is transmitted at high voltages is to increase efficiency. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.

Does an ideal voltage source have current?

By definition, an ideal voltage source is a two-terminal element with the property that the voltage across the terminals is specified at every instant in time. This voltage does not depend on the current through the source. That is, any current in any direction could possibly flow through the source.

Why should a real source not be modeled as an ideal current source in series with a resistor?

To model this as a current source you can’t put a resistor in series because the current source can still generate 1 amp and the open circuit voltage would be infinite.

Why is it important to evaluate sources for reliability?

Finding sources for research is important, but using unreliable sources will hurt your credibility and make your arguments seem less powerful. It is important to be able to identify which sources are credible. This ability requires an understanding of depth, objectivity, currency, authority, and purpose.

Does an ideal current source exist?

Though ideal current sources do not exist, they serve as a model so that we can construct real current sources that mimic as close as possible the characteristics of an ideal current source. What is an Ideal Voltage Source?

How much current does an ideal voltage source produce?

An ideal voltage source will produce or absorb any current needed to maintain the rated voltage. If there is basically no resistance, then that will be a large amount of current. If there is a huge resistance, then it will be a tiny amount of current.

What is a constant current source?

A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. and IR2 = I load which is a constant because Vz is constant. Now don’t you get a hint that a constant voltage source has been deployed in both cases to get a constant current source…??

Why does current always take the path of least resistance?

Current always takes the path of least resistance. Thus, in order for current to go to the path of least resistance, we must set up the source and load so that the source has much higher resistance than the load. This will ensure that the current travels from source to load.
