TAE marg: "If you mean depositing from one plate of copper on another plate or metallic object then the size of the dynamo would depend upon the surface exposed. With any given current the amount of copper deposited will be at the square of the surface. Our 60 light machine can be altered to give 8 volts and 750 amperes price $1,300. From this data you can calculate what you can do.""},{"label":"Author","value":"Wells, J S C"},{"label":"Recipient","value":"Edison, Thomas Alva"},{"label":"Date","value":"1884-02-25"},{"label":"Type","value":"Letter"},{"label":"Subject","value":["Metals and minerals","Dynamos and generators"]},{"label":"Folder/Volume ID","value":"D8403-F"},{"label":"Microfilm ID","value":"71:64"},{"label":"Document ID","value":"D8403Z"},{"label":"URL","value":"https://edisondigital.rutgers.edu/document/D8403Z"},{"label":"Rights","value":"Thomas Edison National Historical Park"},{"label":"Publisher","value":"Thomas A.
