Questions about the Resonance & Q poster

What’s on the Resonance & Q poster?

The rule, 3 worked examples, and the mistake everyone makes. At resonance the inductive and capacitive reactances cancel and the circuit looks pur…; f₀ = 1/(2π√(LC)) · Q = ω₀L/R · BW = f₀/Q; 10 mH with 100 nF = f₀ ≈ 5.03 kHz; Q = 50 at 5 kHz = BW = 100 Hz; Series tank at f₀ = Z = R, current peaks; Common mistake: Expecting a parallel tank to peak in current → A parallel tank peaks…. High Q means a narrow band and large internal voltages: a series tank can develop Q times the source voltage across L.

Who is the Resonance & Q poster for?

Resonance & Q 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 Resonance & Q poster?

Use it to pick L and C for a tuned stage, or to predict a filter's bandwidth. A wall chart earns its place by being glanceable from where the work is happening, so Resonance & Q belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Resonance & Q?

AC Power Triangle, Divider Rules and Capacitor & Inductor Laws sit alongside Resonance & Q 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 Resonance & Q poster free to download and print?

Yes. Resonance & Q 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 Resonance & Q poster print at?

Resonance & Q 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 Resonance & Q loses nothing.Printing guide
