Which of the following device(s) is/are used to interrupt the current flow in a circuit when the current is excessive:

Semi-conductors in their pure state conduct electricity well:

Compressors used in refrigeration applications normally requires motors with _____ starting torque:

A run capacitor improves the running efficiency of the split phase motor:

If the indoor fan speed is not reduced when the compressor speed is reduced, the suction pressure will _______

Starting or large motor cause voltage to drop at the time of starting:

If the voltage supplied by the motor is too low, current drawn by the motor ______:

The _____ is the amperage the motor draws at start-up before the rotor has started to turn

Service factor of the typical motor will be ______:
