2 -(ANSWER)For a high-voltage single-phase AC motor, only 2 motor wires connect to the power lines.
Blow a fuse or trip a thermal overload -(ANSWER)What event is most likely to occur if a motor has an
excessive load.
any -(ANSWER)The total power in any electrical circuit is calculated by finding the sum of the individual
component power consumption.

An increase in downstream pressure -(ANSWER)What causes the poppet of a pressure regulator to
close.
Pa -(ANSWER)The S.I. unit for pressure.
Both are considered fluid systems -(ANSWER)Which is considered a fluid system, pneumatics or
hydraulics.
supply line and actuator line -(ANSWER)The two types of conductors used in a pneumatic system.
springs -(ANSWER)The 5-port, 3-position DCV is held in the mid-position by the springs.
there is a frequent need to connect and disconnect a hose -(ANSWER)Industry uses quick connect
fittings when there is a frequent need to connect and disconnect a hose.
Dust -(ANSWER)Filters should be used on all pneumatic systems because atmospheric air contains Dust.
