10. Excitation losses in a transformer must be determined. When running the test, you should make sure that the secondary winding A. carries exactly the rated current. B. is open-circuited. C. is short-circuited D. carries a higher current than the primary. 11. The armature of a 100-kw 250-volt shunt-wound generator has a resistance of 0.02 ohm. When the generator is operated as a motor, what input voltage should be applied across the brushes to measure the no-load losses if the brush-contact IR drop is 2 volts? A. 240 volts B. 248 volts C. 260 volts D. 252 volts
