Grade 11 · Physics
This quiz helps revise “Electrodynamics” in Physics for grade 11. It has 25 questions in five categories: DC Circuits, Magnetic Field, Induction, AC Power, Oscillations & Waves. Questions get harder as the points go up, from 100 to 500.
The 100- and 200-point questions are open here. The rest show only their first words, and there are no answers: all of that is in the game itself.
