- more tests with dynamometer, commutators off and on; fr. 224 results unclear of tests with commutator on and off 900 foot lb to drive brushes; constants EMF Daniells 1.08 (give solutions); I take the mechanical equivalent of one Weber over one Ohm as 44.3 foot lbs. These are the results of the BA; The half of the weight obtained on the scales must be multiplied by 1.06 to obtain the true strain on the belts; to determine the constant of the tangent galvanometer...; fr. 234 results "92% If the reading on galvanometer ws correct 92% of the power given to the belt driving the Edison was turned into electricity 89% if correction made for tan 2[alpha]"
