The conclusion of the superposition principle is that in a linear system, the net response (such as voltage or current) caused by multiple independent sources acting simultaneously is equal to the sum of the individual responses from each source acting alone, while all other sources are turned off (replaced by their internal impedances).
In simpler terms:
- For voltage sources: If you have multiple voltage sources in a circuit, you can calculate the voltage caused by each source independently, then add them up to get the total voltage.
- For current sources: Similarly, for current sources, calculate the current from each source independently and then sum them to find the total current.
This principle only works for
linear circuits, meaning circuits where components like resistors, capacitors, and inductors behave in a linear fashion (their response is directly proportional to the input).
