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).

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.
What are the differences between Emitter follower and source follower?
no difference between emiter follower and source follower
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).
Do charges move from a source of potential difference into a load or through both the source and the load?
As the circuit must be a closed loop, the current passes through both the source and load. If it was not a closed loop no current could flow anywhere.
What symbol is used to measure potential difference?
V which abbreviates the word volt, which is the unit of measure of the difference in electromotive force (EMF), (or electric potential) between two points of contact; the resulting voltage difference could be direct current (DC) or alternating current (AC) depending on the source of the voltage difference.
Why you need to connect resistor in series for the practical voltage source?
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
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 is difference between cell and diode?
A "cell" (word for part of a battery) is a source of current flow.A diode is a device that restricts current flow to one direction.
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
Describe the relation between the size of your source and electric current?
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
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.
What is the difference between hot and neutral wires in an electrical circuit?
The hot wire carries electrical current to the device, while the neutral wire completes the circuit by returning the current to the power source.
What is alternate current and direct current difference between?
Alternating Current (AC) is the type of electricity typically used in households. With AC, the magnitude and direction of electricity vary. Direct current (DC) is a source of electricity that does not vary in direction. An example of a DC source is a battery, or solar cells. The main difference between the two types of currents is simply the direction, as made quite clear by the names: AC = varied direction and magnitude where as DC = continuous current. Alternate current cannot stored but direct current can be stored examples in case of battery cells
Why do you always use voltage source in lab not current source?
Current is created by voltage (potential difference), not the other way round. It's the voltage - or 'push' - that is making your current move.
What is the difference between a live wire and a neutral wire in an electrical circuit?
A live wire carries electrical current to the device, while a neutral wire completes the circuit by returning the current to the power source.
When is current produced?
Electric current is produced when there is a flow of electric charge in a circuit. This flow of charge is typically generated by a voltage source, such as a battery or power supply, which creates a potential difference that pushes the electrical charge around the circuit.
