In the “Energy in the Environment” section pupils are expected, by use of their practical experience of fuses, circuit breakers and earth wires, to describe the dangers of electricity.
Electrical Circuits
Parallel Circuit Board
The board consists of three lamps arranged in parallel. The current in each branch can be measured as well as the total current in the circuit. The voltage across each lamp can also be measured as well as the voltage across the parallel block.
Series Circuit Board
This board consists of three resistors in series. The current at four points in the circuit can be measured as well as the voltage across each resistor. Suggested activity sheets are included.
