Ideal Independent Current Source Symbol

Figure 1 shows the schematic symbol for an ideal current source driving a resistive load. It is often used as a mathematical abstraction that simplifies the analysis of real electric circuits. Thus if an ideal current source is a 12ma current source the load will receive the entire 12ma.

That is an ideal constant current source continually provides a specified amount of current regardless of the impedance that it is driving and as such an ideal current source could.

Ideal independent current source symbol. The sources can be categorized into two different types independent source and dependent source. Symbol for ideal independent current source the v i plot for an ideal independent current source is depicted below. Practically ideal current source is also not available. A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.

As its name implies a current source is a circuit element that maintains a constant current flow regardless of the voltage developed across its terminals as this voltage is determined by other circuit elements. A current source is a device which provides the constant current to load at any time and is independent of the voltage supplied to the circuit. Ideal current source explained. It can look like that or we could point the arrow the other way like that depending on how the application goes.

Thus as shown in figure 3 the i v characteristic of an independent current source is a horizontal line that cuts through the current axis at a value equal to i s the value of the current source. If the voltage across an ideal voltage source can be specified independently of any other variable in a circuit it is called an independent voltage source. It is denoted by this symbol. An ideal current source provides this constant current with 100 efficiency.

This type of current is known as an ideal current source. There are several voltage sources as well as current sources encountered in our daily life batteries dc generator or alternator all are very common examples of voltage source there are also some current sources encountered in our everyday life such as photo electric cells metadyne generator etc. An ideal independent current source provides a specified current regardless of the potential difference across the terminals of the current source. A current source is the dual of a voltage source the term current sink is sometimes used for sources fed from a negative voltage supply.

The other type of ideal source is called a current source and it also has a symbol with a circle and this one we put an arrow and it goes in the direction of the current. An ideal current source is a current source that supplies constant current to a circuit despite any other conditions present in the circuit. And that s an ideal current source. Similar to voltage sources the charactristic of ideal independent current sources can also be used to solve circuits or a portion of a circuit where an element is in series with a.

An ideal voltage source is a two terminal device that maintains a fixed voltage drop across its terminals. The current symbol is i. It has infinite resistance. V i plot for ideal independent current source.
