Is source transformation unilateral?
Explanation: A source transformation is bilateral because a voltage source can be converted to a current source and vice-versa.
How do source transformations work?
Performing a source transformation consists of using Ohm’s law to take an existing voltage source in series with a resistance, and replacing it with a current source in parallel with the same resistance, or vice versa. The transformed sources are considered identical and can be substituted for one another in a circuit.
In which of the following theorems the source transformation has to be definitely applied?
Source transformations are implemented using Thévenin’s theorem and Norton’s theorem. Source transformation is a technique used to simplify an electric circuit.
How is source transformation carried out in a circuit?
The process carried out here is called source transformation. We have transformed an existing current source with a parallel resistor into an equivalent voltage source with a series resistor. The circuit in Figure 2 can be further simplified as it has a 10 Ω resistor in series with a 5 Ω resistor.
Can a parallel resistor be used for source transformation?
However, there is also a much easier graphical way of achieving this: apply source transformation again! Previously we transformed a current source with a parallel resistor, but we can also apply source transformation to a voltage source with a series resistor. We have two such arrangements, as indicated in Figure 3 (b).
Where is the positive terminal in a source transformation?
Note that the positive terminal of the voltage source is placed to the left, because the current-source arrow was pointing to the left. These two circuits (Figure 1 and Figure 2) are considered to be equivalent: the 1 A current entering node X from node Y has not changed. The process carried out here is called source transformation.
How does the voltage of a circuit depend on the source?
In the case of independent sources, the voltage or current is fixed. If the source is dependent, the value of the voltage or current depends on the amount of current or voltage elsewhere in the circuit. Passive components do not have their own energy.
