What Is Electricity?
A Merton Park Production ‘From the Library of the British Electrical Development Association’
Adapted by Encyclopaedia Britannica Films w/ US commentary
05:00:25 Thunder storm - lightning - trees in wind storm; light in sky above ship mast “St. Elmo’s Fire” - Northern Lights. VO “All these things are examples of electrical phenomena”. Re-enactment of Greek philosopher Thales discovery that rubbing amber w/ piece of fur it would pick up pieces of wool - Dufay’s discovery of rubbing glass as well as amber.
05:02:09 Re-enactment of Benjamin Franklin flying kite in thunder storm. CU spark from key fastened to kite string. Animated diagram of Franklin’s theory of electricity as fluid w/ positive & negative charges. More re-creations of scientific discoveries: Italian scientist Galvani touching leg of dead frog w/ steel knife to make it twitch; Volta experiment w/ discs of copper & zinc separated by cloth - creation of first battery; Ursted discovery of magnetic effect of electric current; Faraday w/ magnet & coil of wire creating voltage.
05:05:01 Modern turbine generators. LS Industrial landscape w/ steam train. Bankside power station in London now Tate Modern - traffic across bridge in FG. Teenage boys look at electrical appliances in store window - television etc. Electric transmission towers or pylons in countryside; sign ‘Danger - 132,000 Volt Lines’. Dalton’s Atomic Theory - table of elements. Simulation of atomic particle. Animated diagram of interior of atom w/ nucleus & electrons.
05:08:44 Copper wire - animated diagram of copper atom & electrons compared to uranium & hydrogen. Man removes flashlight battery; high angle shot interior power station. Electric current animations (GOOD). Electrical circuit diagram.
05:11:42 Narrator summarizes main points of film re movement of electrons “which makes the electricity Men use in their daily lives...”
