Question 309Electricity & Electronics - QMED

The correct answer is D) across-the-line starter. The across-the-line starter is the most common type of motor starter used for Coast Guard Captain's License Examinations. It directly connects the motor to the full line voltage, allowing the motor to start at full torque. This is the simplest and most straightforward motor starting method, making it the preferred choice for the exam. The other options, such as part-winding, autotransformer, and primary-resistor starters, are more complex and used in specific applications. They are less likely to be encountered in the context of the Coast Guard Captain's License Examination.
