Superposition Theorem Example //
Using Superposition theorem, find the current through the 2Ω resistor of the network of Figure 1 above. The presence of three sources will result in three different networks to be analyzed.
Considering the effect of the 12-V source (Fig. 2):
Considering the effect of the 6V source (Fig. 3):
Considering the effect of the 3A source (Fig. 4):
Applying the current divider rule,
The total current through the 2Ω resistor appears in Fig. 5, and
