Tutorial on Superposition - Part 1

Superposition is a powerful theorem that allows the engineer to break up a large, difficult problem into several small, simple problems.

Consider the circuit below.

We want to find I₀.  This could be done by using such techniques as the node voltage method or the mesh current method.  Instead, we will solve it using superposition.

Calculate the contribution of the 480 V source to I₀.
