Superposition Theorem

The superposition principle is a fundamental concept stating that in a linear circuit, the voltage across (or current through) an element can be determined by summing the individual contributions of each independent source acting in isolation. When dealing with linear circuits containing multiple independent sources, this principle serves as a v...

The superposition theorem is used in circuits with multiple independent sources.

To apply this theorem, keep one independent source at a time while replacing the inactive voltage source with a short-circuit and the inactive current source with an open-circuit, respectively.

The theorem states that the voltage across or the current ...
