Going with the flow: Using analogies to explain electric circuits Going with the flow: Using analogies to explain electric circuits.
Electronic circuits usually use direct current sources. The load of an electronic circuit may be as simple as a few resistors, capacitors, and a lamp, all connected together to create the flash in a camera. Or an electronic circuit can be complicated, connecting thousands of resistors, capacitors, and transistors. It may be an integrated circuit such as the microprocessor in a computer.
The circuit breaker will open, or "break", the circuit when the current in that circuit becomes too high, or the fuse will "blow". This gives protection.
We tour schools offering either single project days, or more extended project work over many weeks and combining multidisciplinary work, mainly to students aged 11 to 14. Through the construction of these cars students learn about electrical circuits and how solar energy functions.
