44. What will happen to the armature if the shunt field opens while it’s operating with no load (page 90)?
45. Loose coils can lead to a grounded or open circuit (page 91). T_ F
46. An open coil in a two-parallel circuit shunt field will
of the shunt field (pages 91-92).
a. lower the resistance
b. raise the resistance
47. An insulation breakdown between the shunt and series fields is usually caused by high amperes in the series field (page 94). T_ F
48. Running a compound DC machine without the series field is a quick way of ruling out the series field as the problem (page 94). T_ F
49. The resistance of the series field has very little effect on the amperes of its circuit (page 94). T_ F
50. A grounded series field coil may not show a problem (page 95). T_ F
51. The shunt field should never have AC voltage applied to it, because the series field will be destroyed by the high voltage being transformed into it (page 97). T_ F
52. Leads Fl and F2 are usually larger than the rest of the DC machine’s leads (page 99). T_ F
