I was invited to do a power point presentation at Finlayson Park School, Manurewa, New Zealand, yesterday, and talked about Electricity, where it comes from, safety around electricity, and did a couple of electrical experiments as well.
The experiments were:
1. Showing magnetism with an open core transformer.
2. The importance of correct fuses or circuit breakers, and the potential consequences.
3. Some 4400 Volts sparks with a small home made power pole and overhead lines set up.
Copper - green arcs
Aluminium - blue arcs
4. A demo that a tree is live when it touches a power line. (Stay well away if that happens in real life).
5. And a grapefruit was fried and sparkled.
The fuse pop (which you couldn't see here) and the magnetic core experiment I will redo and attach a link to later.
Повторяем попытку...
