What are the operational characteristics of the split phase motor shown in figure "A" of the illustration? Illustration EL-0215

AI Explanation
The correct answer is C) The motor is reversible and dual-voltage, configured for low volts.
The split-phase motor shown in the illustration is a type of AC motor that can be reversed by switching the connections of the start and run windings. Additionally, dual-voltage motors can operate on either a high or low voltage supply. In this case, the configuration is for low voltage operation, which is common for smaller fractional horsepower motors used in many marine applications.
The other options are incorrect because A) describes a high voltage configuration, B) indicates the motor is non-reversible, and D) specifies a high voltage configuration for a non-reversible motor, which does not match the characteristics of the split-phase motor shown.
