Superposition in CircuitsHardQuestion 31636

Question

The superposition principle in circuit analysis states:

A
Total power = sum of individual powers
B
Total current from each source acts independently and results are superposed
Correct
C
Kirchhoff's laws do not apply
D
Resistances add in parallel

Correct answer

Total current from each source acts independently and results are superposed

Explanation

For linear circuits, we can analyse one independent source at a time (others replaced by their internal resistance), then add the currents/voltages from each analysis.
