The chapter list on this page is still real: it was read from /var/task/data/syllabus/class10.json on this machine, which ships with the repo. Asking questions and taking quizzes need the API, so those are unavailable until it is running.

Concept animations for this chapter

Interactive explanations, drawn in the page — no video, no external scripts. Each one is keyboard operable, has a “what to notice” caption, and a “try this” prompt that changes what it shows.

Ohm’s law: current from voltage and resistance, and the V–I graph

conceptId: ohm-law

What to notice: current = V / R = 1.20 A, so doubling the voltage doubles the current and doubling the resistance halves it — the recorded points fall on a straight line through the origin whose slope is 1/R.

Try this: record readings at 2 V, 4 V and 6 V with R = 5 Ω, then set R = 10 Ω and record again — the second set of points lies on a shallower line. Model note: the resistor is treated as ohmic at every voltage; battery internal resistance, wire resistance and any heating of the resistor are not modelled.

live values — V: 6.0 V, R: 5.0 Ω, I: 1.200 A, P: 7.20 W, readings: 0
