Lessons Physics
How things really work
Short, hands-on lessons for curious adults. Each takes about 15 minutes: six steps to play with in 3D, then a quick quiz.
-
01 · Basic electric circuits
What really happens when you flip a light switch: loops, voltage, current and resistance, series and parallel, fuses.
-
02 · Electricity at home
Understand your bill, and what keeps you safe: watts, kilowatt-hours, AC, the wires in a plug, overloads, earth and RCDs.
-
03 · Magnets and magnetic fields
Why magnets attract and repel, the invisible field, why a compass points north, and how a current makes a magnet you can switch off.
-
04 · Motors and generators
How a current in a magnet's field makes a push, how a motor keeps spinning, and how turning a coil makes the electricity in your sockets.
