I remember The Science Museum from a visit about 53 years ago with my dad. The thing I remember to this day is the flashover of a 132kv pylon insulator with an exceedingly loud bang. This was done twice!
The phrase I recall is "capacitors charged in parallel and discharged in series".
A return visit around 9 years ago with my grandson, all I remember is the operation of a steam engine and all the young people trying to get you to pay a "suggested donation" for admittance.
