Superposition in Circuits, step by step

Linear elements only. The method fails the moment a diode appears.

  1. Check linearity firstR, L, C and dependent sources qualify. Diodes and saturating cores do not.
  2. Keep one source aliveZero every other independent source: short voltages, open currents.
  3. Solve the simplified circuitFind that source's contribution to the one branch you actually care about.
  4. Repeat for each sourceOne pass per independent source, keeping the same sign convention throughout.
  5. Add the contributionsAlgebraic sum, with sign. That total is the real branch current or voltage.

Superposition adds currents and voltages, never powers. Power is quadratic in the variable, so contributions do not add.

Who is the Superposition in Circuits poster for?
Superposition in Circuits belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning circuit analysis can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Superposition in Circuits poster?
Useful when a circuit mixes DC bias with a signal, or several independent sources. A wall chart earns its place by being glanceable from where the work is happening, so Superposition in Circuits belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Superposition in Circuits?
AC Power Triangle, Divider Rules and Capacitor & Inductor Laws sit alongside Superposition in Circuits in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AC Power TriangleDivider RulesCapacitor & Inductor Laws
Is the Superposition in Circuits poster free to download and print?
Yes. Superposition in Circuits downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Superposition in Circuits poster print at?
Superposition in Circuits is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Superposition in Circuits loses nothing.Printing guide
