SUPERPOSITION THEOREM

Definition: A linear network which contains two or more independent source can be analyzed to obtain the various voltages and branch currents by allowing the source to act one at a time, then superposition one at the time.

The principles apply of the linear relationship between current and voltages are:

1.      The 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.

2.      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).
