Questions about the Potential Dividers poster

What’s on the Potential Dividers poster?

The rule, 3 worked examples, and the mistake everyone makes. The output voltage is the supply times the ratio of the output resistor to the total…; Vout = Vin × R₂/(R₁ + R₂); Two equal resistors = Half the supply; Thermistor in the divider = Output varies with temperature; LDR in the divider = Output varies with light; Common mistake: Ignoring the load connected to the output → The load is in parallel w…. A thermistor's resistance falls as temperature rises. Which way the output moves depends on which side of the divider it is on.

Who is the Potential Dividers poster for?

Potential Dividers belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning electromagnetism can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Potential Dividers poster?

Voltage divides in proportion to resistance. That is the whole circuit. A wall chart earns its place by being glanceable from where the work is happening, so Potential Dividers belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.

What other posters go with Potential Dividers?

AC Circuits, Capacitance and Circuit Basics sit alongside Potential Dividers in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AC CircuitsCapacitanceCircuit Basics

Is the Potential Dividers poster free to download and print?

Yes. Potential Dividers downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics 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 Potential Dividers poster print at?

Potential Dividers 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 Potential Dividers loses nothing.Printing guide
