Wasu a Source Transformation?

An electrical source transformation (or just ”source transformation”) is a method for simplifying circuits by replacing a voltage source with its equivalent current source, or a current source with its equivalent voltage source. Source transformations are implemented using Thévenin’s theorem and Norton’s theorem.

Source transformation ita ce aikin da ake amfani da shi don koyar wasan kafuwa.

Za a nuna hakan cewa yana aiki da misalai.

A baka voltage source ta hanyar resistance connected in series tare da shi.

Wannan resistance na series yana nufin internal resistance na voltage source mai sauƙi.

Tana, zama a short circuit output terminals na voltage source circuit kamar yadda aka bayyana a cikin wannan,

Daga baya, a yi Kirchhoff Voltage Law a cikin wannan circuit, muka samu,

Idan, I ita ce current na voltage source idan an short circuit shi.

Tana, za a baka current source na current I wanda ya ba da open-circuit voltage a cikin terminals na open,

Daga baya, a yi Kirchhoff Current Law a node 1, na circuit, muka samu,

Daga (i) da (ii) muka samu,

Open circuit voltage na duka sources ita ce V da short circuit current na duka sources ita ce I. Wannan resistance connected in series a cikin voltage source ita ce connected in parallel a cikin current source.

Saboda haka, wannan voltage source da current source suna da muhimmanci waɗanda suka fi sani.

Current source ita ce dual form na voltage source da voltage source ita ce dual form na current source.

Voltage source zai iya canza zuwa equivalent current source da current source zai iya canza zuwa equivalent voltage source.

Voltage Source to Current Source Conversion

Assume a voltage source with terminal voltage V and the internal resistance r. This resistance is in series. The current supplied by the source is equal to:

idanci, a short circuit terminals na source.

Wannan current ita ce an supply da equivalent current source da kuma resistance r ita ce an connect across source. Voltage source to current source conversion ita ce a cikin figure na biyu.

Current Source to Voltage Source Conversion

Similarly, assume a current source with the value I and internal resistance r. Now according to the Ohm’s law, the voltage across the source can be calculated as

Hence, voltage appearing, across the source, when terminals are open, is V.
