| Superposition Theorem |
The Superposition Method is a way to determined the currents in a circuit with a multiple sources by leaving one source at a time and replacing the other sources by their internal resistance. The strategy used in the Superposition Theorem is to eliminate all but one source of power within a network at a time, using series/parallel analysis to determine voltage drops (and/or currents) within the modified network for each power source separately. Then, once voltage drops and/or currents have been determined for each power source working separately, the values are all “superimposed” on top of each other (added algebraically) to find the actual voltage drops/currents with all sources active. Let's look at our example circuit again and apply.
| Principle of Superposition: |
In a linear circuit containing multiple independent sources, any output (voltage or current) in the circuit may be calculated by adding together the contributions due to each independent source acting alone.
| Procedures: |
1. Determine contribution due to an independent source. Set all other independent source values to 0.
2. Repeat for each independent source.
3. Sum individual contributions to obtain desired output.

| My Learning Experience XD |
I learned that in superposition theorem states that a circuit can be analyzed with only one source of power at a time, the corresponding component voltages and currents algebraically added to find out what they'll do with all power sources in effect and to negate all but one power source for analysis, replace any source of voltage (batteries) with a wire; replace any current source with an open (break). I noted also that it should be consider one independent source at a time while all other independent sources are turned off (deactivated, killed).Lastly superposition cannot be used directly to find power.
