What’s on the Electric Fields poster
A 4-row table: Quantity · Radial (point charge) · Uniform (plates).
Radial against uniform fields.
- Field strength E — kQ/r² — V/d
- Potential V — kQ/r — Varies linearly
- Force on charge q — qE — qE
- Field lines — Radiate outward — Parallel, evenly spaced
Field strength is the gradient of potential: E = −dV/dr. Field lines always run from high to low potential.
Questions about the Electric Fields poster
- What’s on the Electric Fields poster?
- A 4-row table: Quantity · Radial (point charge) · Uniform (plates). Radial against uniform fields. Field strength E — kQ/r² — V/d; Potential V — kQ/r — Varies linearly; Force on charge q — qE — qE; Field lines — Radiate outward — Parallel, evenly spaced. Field strength is the gradient of potential: E = −dV/dr. Field lines always run from high to low potential.
- Who is the Electric Fields poster for?
- Electric Fields 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 Electric Fields poster?
- Radial fields obey an inverse square. Uniform fields do not vary at all. A wall chart earns its place by being glanceable from where the work is happening, so Electric Fields belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Electric Fields?
- AC Circuits, Capacitance and Circuit Basics sit alongside Electric Fields 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 Electric Fields poster free to download and print?
- Yes. Electric Fields 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 Electric Fields poster print at?
- Electric Fields 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 Electric Fields loses nothing.Printing guide
