A switch in a open position - Infinite What does FLA stand for - Full loaded Amps When does the motor draw FLA - When the motors are running (full speed) I need to shut off the power before measuring - ohms infinite infinite 10 - one open one good name two motors that do nut use capacitors - Shaded pole and split phase electrically what does the capacitor do to the circuit - increases a electrical path exist between motor winding and the housing of the motor - grounded which would be brighter 3 lights in series or 3 in parallel - parallel which motor would be used for a small single fan - shaded pole the shorted switch would read what in the on position and what in the off position - zero in both positions another name for the front and back plates to hold the motor - end bells 3, 6, 9 common to start - 6 switch in closed - 0 start winding run winding run capacitor - PSC run winding - shaded pole how long is a run winding energized in a split phase - 100% 0 infinite infinite - one open one short how to change direction to reverse in split phase - reverse start winding what is electrical pressure - voltage which motors use run caps - PSC and CSCR electrically what does a start cap do to the motor - increase starting torque Are winding part of poles or pole part of winding - poles part of winding current flow in one direction only - DC
