Title
[D8330W], Letter from William Symes Andrews to Thomas Alva Edison, April 21st, 1883
Editor's Notes
"I will attend to the test on E dynamo as per yoru letter of yesterday as soon as possible--" What should I do with the large insulated copper brushes I got yesterday; they're for C dynamo and I can't test them on a smaller one. Tested 450 light dynamo today; field mag is abt 8 ohms. As presently configured, 450 lamps is a vy high load. Reduce armature resistance by putting another wire on it thus drop resistance to 0.012 ohms and can carry the load fine. TAE: "cannot another wire be put on= In village plant station it will only have to carry 450 for 3 1/2 hours before & after that the Load aint 1/2 450="
