#11 10. Excitation losses in a transformer must be determined. When running the test, you should make surethat the secondary windingA. carries exactly the rated current.B. is open-circuited.C. is short-circuitedD. 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 thegenerator is operated as a motor, what input voltage should be applied across the brushes to measure theno-load losses if the brush-contact IR drop is 2 volts?A. 240 voltsB. 248 voltsC. 260 voltsD. 252 volts

Given: The armature is 100 kW The voltage is 250 VThe resistance is 0.02 ohm Brush contact voltage…
