o find thetotal power supplied by the machine, the apparatusmay generally be so adjusted as to satisfy this condition.All we need do is to work the transformer or motor Bat a lower voltage than that of the machine. But if theproblem is to determine the power taken by the trans-former or motor B,… … 666666 may be used. This was devised by Dr. Fleming, and isknown under the term Three Ampere Meter Method.Its application will be understood on reference to Fig. 81,where A is the alternator, and a, a^ and «2 ^Ie ampere-meters indicating respectively the total current and itstwo components which…
