I think our dear teacher has pressed the wrong button on the EVM (he has got the indelible on his fingers) and he seems frustrated and feels guilty for it in the whole lecture except when in end he says "We hope this session was informative and enjoyable. Thank You." as if now he is absolved of his grief after doing something substantial. :) I mean he doesn't look happy at all it seems the whole lecture was shot with him on the gun point. Edit:- PJs aside The content is good and u need to watch it in 1.5x atleast.
very informative, if we use kerosene as dielectric it will get fire where the electrode and work piece will contact each other, when it will produce the sparks
