Why is source conversion needed?
Source transformation methods are used for circuit simplification to modify the complex circuits by transforming independent current sources into independent voltage sources and vice-versa. This source transformation method can also be used to convert a circuit from Thevinin’s equivalent into Norton’s equivalent.
What is meant by source transformation?
Source transformation is the process of simplifying a circuit solution, especially with mixed sources, by transforming voltage sources into current sources, and vice versa, using Thévenin’s theorem and Norton’s theorem respectively.
What is current source how it is converted into voltage source?
Conversion of Current Source into Voltage Source In the above circuit diagram a current source which is connected in parallel with the resistance is transformed into a voltage source by placing the resistance in series with the voltage source.
When can we apply source transformation?
Source transformation is applicable even for the circuits which have dependent sources. Let’s consider the circuit shown in Figure 7(a). Here, one needs to resort to source shifting for the 3 A current source before applying source transformation.
How do you use source transformations with dependent sources?
A dependent source is simply one whose current or voltage is not a constant, but a function of some input parameter x. So in the source transformation algebra, you simply regard the quantities V and I not as constants but as V(x) and I(x); in other words V(x)=I(x)R and I(x)=V(x)R.
What happens when you change the current source to AC?
Every so often, the electrons change direction. In alternating current, the electrons don’t move steadily forward. Instead, they just move back and forth. When the electrons in alternating current switch direction, the direction of current and the voltage of the circuit reverses itself.
What is source transformation and source shifting?
Shifting of current source within the network is undertaken so as to make the given electrical circuit suitable for current-to-voltage source transformation. The reason for this is that, while shifting the current source, we have to maintain the same current at all the nodes of the associated network.
Why current source is replaced by open circuit?
Both the sources replaced by its internal resistance… Voltage source have internal resistance equal to zero,hence it replaced by short circuit. While current source having internal resistance equal to infinity. Hence current source is replaced by open circuit.
Can we convert dependent current source to voltage source?
Yes, we can apply source transformation to dependant sources. Analysis of the circuit remains same as that of independent sources. While source transformation, dependent current source will be converted to dependent voltage source and vice versa.
Where do we need this transformation of voltage in electrical engineering?
There are two types of sources: Voltage source and Current Source. Therefore, this technique will convert voltage source into equivalent current source and current source into equivalent voltage source. This kind of transformation is required to solve circuit network.
