| Title | Letter from [William George] Armstrong, Cragside, Rothbury, to [Alan Archibald Campbell] Swinton, 66 Victoria [Street], London, S.W |
| Creator | Armstrong; William George (1810 - 1900); Baron Armstrong of Cragside; armaments manufacturer and industrialist |
| Date | 25 November 1890 |
| Description | Expresses interest in the results of Campbell Swinton's experiments involving three induction coils but admits they puzzle him. Struggles to understand why a defect in one of three coils connected in a series should be different in result from a defect in a corresponding section of a single coil equivalent in power to the three, discussing his thoughts. Wishes to know whether the defective coil impairs the action of the other two, when the three are connected and parallel, enquiring about sparks. Intends to discuss the topic further when he next visits London. |
