The superposition theorem is a very important concept in the circuit theory. If a circuit has two or more independent sources, one way to determine the value of a specific variable (voltage or current) is to use nodal or mesh analysis.Another way is to determine the contribution of each independent source to the variable and then add them up.

The superposition theorem tell us that any voltage or current in a circuit is the algebraic sum of the voltages and currents caused by each independent supply by itself. In practice, this means we have to analyze a circuit once for each independent supply in the circuit. The process is detailed below and then applied to a number of examples.
Fortunately, all of components we have discussed; resistors, capacitors and inductors, fall into that category. Further, superposition cannot be used to find values for non-linear functions, such as power, directly. This is not a limitation though because power can be computed from the resulting voltage or current values.

A capacitor is a linear component because voltage and current as functions of time depend in a linear way on each other. In the context of relations of two functions (of time) to each other (and not just values at one instance of time) linearity means that the principle of superposition holds (as Neil_UK has pointed out).
