Grade 8 · Physics
This quiz helps revise “Electric current” in Physics for grade 8. It has 25 questions in five categories: Current and Circuits, Measuring Electricity, Wires and Devices, Circuit Connections, Energy and Safety. 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.
