| X4008 P.C.118. Contd. -2- Miscellaneous observations. With the resistance inserted in the field circuit, the field current is reduced by approximately one third; i.e. from 3 amperes to 2 amperes. Although the resistance gets hot to the touch it appears to be able to carry 2 amperes safely. EFC/C.A.Pignatt. | ||
