Superposition Theorem

Exactly matches Figure 1.7.7 and the worked example in the ADI Electronics Textbook, Chapter 1.

Live Circuit (polarity-aware current arrows)

Only V1 Active (V2 shorted)

V2 replaced by wire • R2 || R3 then + R1
IR1 = 3.845 mA    VR1 = 1.538 V
IR2 = 7.69 mA    IR3 = 11.54 mA
(polarity per KVL)

Only V2 Active (V1 shorted)

V1 replaced by wire • R2 || R3 then + R1
IR1 = 5.00 mA    VR1 = 2.00 V
IR2 = 3.00 mA    IR3 = −2.00 mA
(signs matter!)

Superimposed Result (Both Active)

IR1 = −3.845 + 5.00 = 1.155 mA
IR2 = 7.69 + 3.00 = 10.69 mA
IR3 = 11.54 + −2.00 = 9.54 mA
Matches wiki Table 1.7.4 exactly at defaults

Superposition works only for linear bilateral networks. It does not apply to power or to circuits with diodes/transistors.
