Tutorial on Superposition - Part 2

That's right.  You start from the original circuit.

Then you redraw the circuit with the 12 A source and the 720 V source removed; here's what you get:

Now it's clear that the 100 W and 140 W resistors are in series, and the 150 W resistor is shorted out.
I₄₈₀ = 480/(100 + 140) = 2 A

Let's move on to the next source.  Calculate the contribution of the 12 A source to I₀.
