Question about superposition

[Molondo]

When using more problematic circuits, we use superposition. I forget, when you have 2 sources, one which is a voltage and the other is current. When using the the voltage as the source you make the current source open? and when using current, make the voltage source short?

thanks

Superposition
In any linear circuit containing multiple independent sources, the current or voltage at any point in the network may be calculated as the algebraic sum of the individual contributions of each source acting alone.

Procedure:

For each independent voltage and current source (repeat the following):
Replace the other independent voltage sources with a short circuit (i.e., v = 0).
Replace the other independent current sources with an open circuit (i.e., i = 0).
Note: Dependent sources are not changed!
Calculate the contribution of this particular voltage or current source to the desired output parameter.
Algebraically sum the individual contributions (current and/or voltage) from each independent source.

Easy, what's the equivalent of zeroing out the source? Zero volts is the same as the voltage drop across a short while zero current is the same as an open circuit.

Superposition states that layers farther down in the archaeological record are older...
