!!! example
Halving voltage must halve current (or at least halve it relative to a base current / voltage).
### Superposition
In linear circuits, the superposition principle states that the voltage/current through an element is equal to the sum of the voltages/currents from each independent source alone.
$$
v=\sum v_x \\
i=\sum i_x
$$
To do so, each unused independent source should be replaced with a short circuit (voltage) or an open circuit (current).
