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.
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.
Don’t try this at home.
A very thorough analysis of the power vs cost relationship for common batteries. http://www.wired.com/2012/01/are-expensive-batteries-worth-the-extra-cost/
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
[swf:http://vcephysics.com/flash/swf/circuit.swf 600 550 white wmode] This object shows the relationship between current & voltage when changing resistance. The differences in current and voltage relationships can be seen. Drag the red sliders to change the resistance between 1 & 100Ω and … Continue reading
