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

http://www.bbc.co.uk/britainfromabove/stories/people/teatimebritain.shtml Power surges called the TV pickup are unique to Britain. The engineers at the National Grid control centre brace themselves each time Eastenders ends and 1.75 million kettles get switched on.
As power generation becomes increasingly mixed and demand increases, what does the grid of the future look like? http://www.bbc.co.uk/programmes/p0268cd5
(View in full window) This animation shows the operation of a transformer, designed to step voltages up or down for more efficient & safer transfer of energy. The primary & secondary wires are wrapped around a solid iron core. Changing … Continue reading
(View in full window) This animation shows the turning effect (torque) acting on a DC motor through its rotation. You can use the right-hand slap or Fleming’s left hand rule to find the direction of rotation. Downloads: Flash source file … Continue reading
