Physics topic
Electricity & magnetism simulations
Build understanding of current, resistance, fields and induction with circuits, motors, generators and electrical measurement labs.
Where does electrical energy go?
Start with a DC circuit and measure current as voltage changes. Then compare a motor and generator: identify the energy input and output in each system.
- Voltage, current and resistance
- Electric and magnetic fields
- Electromagnetic induction and AC
