Oxford lecture begins with a blooper

[Andrew Palfreyman]

E = 0.5 C V^2.
E = 100 kJ
C = 75 mF
V = 45 kV

These numbers on the LPPFusion slide @10:38 do not compute.

Good catch–it is two typos–The font is wrong on the capacitance–should be symbol “mu” for micro farad, not “m” for millifarad. Also, the capacitance is for 8-capacitor configuration, while the energy is for 12-capacitor. For 12 capacitors, the correct C is 113 microfarads–then the formula looks right. (We rounded 114 kJ to 100 kJ)

Funny you were the first to notice it 9 months later. It is in the video, so I guess the only way to correct it is in the caption for the video.

Being an Oxford alumnus myself, I felt it was my duty 🙂
