Photonicinduction and Polar again take control of the power supply but this time test an Electric Kettle to it’s limits and beyond, the speed and power is surprising.
Watch a soda can rip itself apart in a fiery explosion at 11,000fps with a Phantom high speed camera. Running a current through a coil, produces an electromagnet. Turn up the voltage in this experiment, and make that current strong … Continue reading
One of the many great learning objects from Walter Fendt (http://www.walter-fendt.de/html5/phen/index.html).
